Thomas was born in Virginia. His parents are not definitely known. A source that claims access to records from his family Bible says he was the son of Revolutionary War cavalry soldier George Watson and Margaret Murphy from Pittsylvania County, Virginia, who moved to Robertson County, Tennessee in 1814 and established a plantation there. This page relies on that source for its account of his early years. However, there was another Thomas H. Watson from Virginia of similar age who married one Sally Hardin and settled in Kentucky.
Margaret was born in Ohio. One unsourced account names her parents as Thomas C. Davis and “Indian” Davis, which is not much to go on. She had a younger sister Sarah Ann (1825-3 Sep 1860), who about 1842 married Ephraim Jellison (~1816-185x) from Pennsylvania.
By the early 1830s, for whatever reason, Thomas had traveled north to the Ohio valley. He reportedly married Margaret on 17 Nov 1833, probably near Piqua, Miami County, Ohio. Their first three children were born in Ohio. Of all the Thomas Watsons to appear in the 1840 Ohio census, the one most likely to have been him was the young man in Cincinnati, with a wife in her twenties and a boy and girl under 5. No way to be sure, though. He was living next door to John Watson, a family man in his forties – older brother, father, coincidence, who’s to say? Records for George Watson and Margaret Murphy don’t list a son named John.
In the early 1840s, Thomas moved west to Adams County, Indiana just over the Ohio border, where his and Margaret’s four younger children were later born. The 1850 census showed them in Hartford, Adams County: Thomas (30, laborer) and Mary (26), with children Sarah (14), George (12), William (7), James (4), and Mary (2). It incorrectly listed Thomas as born in Ohio and all the children as born in Indiana. It also omitted son John.
In the early 1850s they moved again, 30-40 miles south to Randolph County. Margaret died there in 1853. She’s buried in Whiteriver Cemetery, Randolph County, Indiana. Son James, who died in 1858, is buried with her.
On 5 Aug 1855, Thomas married Sarah Ann “Ann” Davis Jellison (1825-3 Sep 1860), the widowed sister of his late wife, in Randolph County, Indiana. They had two children:
Margaret A. “Maggie” (1 May 1857-7 Aug 1947) — m. George Riley Spillers on 1 Nov 1884
Martha Mariah (16 May 1859-15 Jan 1897) — m. Louis A. Carter in 1877
In late 1859, Thomas, Ann and their combined families, including Thomas’s son George and his new bride, traveled west to Muscatine County, Iowa for an extended visit with Thomas’s daughter Sarah Watson Delong and her family. Then they moved to Bowling Green, Pettis County, Missouri, where the 1860 census found them: Thomas (46), Ann (34), and children William (17), Robert (14), Lewis (12), Mary (12), Samuel (9), Margaret (3), and Martha (1). Robert and Lewis were Ann’s sons by her previous husband; William, Mary, and Samuel were Thomas’s and Margaret’s children; and Margaret and Martha were Thomas’s and Ann’s children. Okay, but why were all the children listed as born in Iowa? I get the impression that Thomas wasn’t real particular about what he told census-takers.
The family-Bible source says that Thomas planned to move the family further west to Kansas, but changed his mind after Ann’s death on 3 Sep 1860, and instead moved southeast to the area of Dixon, Pulaski County, Missouri. Within a few months of their arrival, Thomas met Eliza Matilda Carter (1838-1881) from Tennessee, younger sister of Clark ancestor Sallie Carter. They married on 7 Feb 1861. They had six children:
Sarah Jane (6 Feb 1863-6 Feb 1863)
Tabitha Elizabeth “Lizzy” (7 Sep 1864-16 Sep 1960) — m. Joseph Carter on 22 Aug 1880; m. Felix Bledsoe in 1910
Nancy E. (~1868-????)
Henry T. (28 Nov 1869-10 Oct 1887)
Manervia Angelina (26 Feb 1872-19 Feb 1942) — m. James Monroe Ragan in 1899
Joseph Marion “Joe” (26 Apr 1874-19 Sep 1954) — m. Eliza Clarinda Keaton in 1896
The 1870 census for Miller Township, Maries County, Missouri listed Thomas (58, although the transcription turns it into 38) and Elisa (32) with children Margaret (14), Martha H. (12), Tabitha E. (7), Nancy E. (3), and H. G. (1). Thomas’s stepson Robert Jellison (1843-????) was listed as “Robb Watson” (27). Also with the family was Elizabeth Carter (78) from Tennessee. This was Elizabeth Howard Carter, Eliza’s mother. She was also the mother of Clark ancestor Sallie Carter, hence grandmother of Clark ancestor Lewis Kelley. Son John Watson (30) and his wife were next door.
The 1880 census for Miller Township listed T. H. Watson (68) and wife Matilda (44) with children Tabitha E. (16), Nancy E. (12), Henry T. (10), Menerva A. (7), and Joseph (5). Also with them were Thomas’s stepson Robert Jellison (34) and a widower named George Murphy (56, from Kentucky) – maybe a relative on Thomas’s mother’s side, if Peggy Murphy was indeed his mother.
Thomas died later that same year. He’s reportedly buried in Fairview Cemetery, Shantytown, Maries County, Missouri, but the exact location of the grave is unknown. Eliza died the following year, and is buried with Thomas, grave location likewise lost.
Sarah married William DeLong (1822-12 Jul 1899) from West Virginia (Virginia, at the time) in 1854 in Indiana. They moved to Moscow Township, Muscatine County, Iowa soon after, accompanied by William’s sister Harriet. The first four of their ten children were born in Iowa:
James Baxter (1856-19xx)
John W. (~1859-1950) — m. Clara A. Evans
William Henry (9 Oct 1861-14 Sep 1946) — m. Ida Sophia Freberg on 9 Mar 1891; m. Elva Hillman Moon on 27 Dec 1903

Mary Ellen (~1868-????)
Thomas Adelbert “Delbert” (20 Jan 1870-12 Sep 1919)
Etta Jane “Jennie” (24 Sep 1872-2 Mar 1962) — m. John H. Murray on 17 Jan 1895; m. William Henry Root in 1915
Matilda “Tillie” (28 Nov 1875-Jun 1963)
Frederick Sherman (Sep 1878-1934) — m. Jennie Maude Riddle in 19xx
Sarah Elizabeth (1881-1940) — m. Robert H. Banner on 22 Jun 1902
William served in the 3rd Iowa Cavalry during the war. After the war, the family moved to Doniphan County, Kansas. William died in 1899, and is buried in Mount Olive Cemetery, Troy, Doniphan County. In 1900, Sarah was living with four of her children. In 1910, she was living in Randolph, Riley County, Kansas with Delbert and Matilda. In 1920, she was with James and Matilda in Jackson, Riley County. Sarah died in 1934 and is buried with William.
George married Martha Elwood (1840-30 Mar 1870) on 26 Sep 1857. They settled in Farmland, Monroe Township, Randolph County, Indiana, remaining there after George’s family headed west to Missouri. Known children:
William Henry (~1859-5 May 1928) — m. Mary Maxine Wasson on 31 Dec 1880
Rosetta “Rose” (Aug 1864-18 Jul 1940) — m. Rudolph Charles Litschert about 1881
Flora A. (1867-9 Sep 1944) — m. William Harvey Taylor
Martha died in 1870, and is buried in Cedar Cemetery, Randolph County. George married Abigail Miller (1847-1928) on 30 Jul 1870. From around this time, he ran a grocery store (that twice burned down). He was also postmaster of Farmland, Indiana. Known children with Abigail (Flora’s obituary listed Abigail as her mother, but her year of birth disagrees):
Dollie Arabell (21 Sep 1871-2 Jan 1962) — m. Jeremiah Patrick Cronin on 20 May 1895
Carl W. (11 Apr 1878-Jan 1956) — m. Bertha Jeanetta Smithson on 18 Jun 1899
In 1880, George’s half-sister Margaret (22) was staying with them. In 1900, the household included Abigail’s older sister Ellen and son Carl’s wife Bertha. George died in 1920, and is buried in Woodlawn Cemetery, Maxville, Randolph County, Indiana. Abigail died in 1928 and is buried with him.
John volunteered for Company A, 28th Illinois Regiment at Havana, Illinois on 1 Aug 1861. After three years, he re-enlisted. He lost an eye during the war, and was mustered out in 1866. He married Martha Jane Rollins (2 Oct 1842-22 Jan 1906), a grand-daughter of Clark ancestors Levi Carter and Elizabeth Howard, on 17 Dec 1868. They had five children:
Mary Ellen (1874-1960) — m. William “Doc” McGirr about 1893; m. William Albert Wright after 1929
John Wesley (1 May 1876-13 Jun 1946) — m. Naomi Ann Cantriel
William Harvey (5 Feb 1878-10 Jun 1956) — m. Stella M. Jones
James Marion (15 Aug 1880-20 Apr 1950) — m. Lucinda Frances ???
Benjamin F. (~1883-19xx) — m. Alpha Rhea Beatty in 191x
The 1870 census showed them in Miller, Maries County, Missouri next door to John’s father and family, no children yet. The 1880 census showed them in Dry Creek, Maries County with their first three children and some woman named Fanny Gather (33). In 1900, they were in Richwood Township, Maries County. Martha died in 1906. In 1910, John was living with his married daughter Mary in Pulaski County. His youngest son Benjamin was living with his maternal uncle William Rollins. Soon after, John married Nancy Alice Leek (12 Feb 1850-23 Jun 1925), widow of William Goleanor. John died in 1913, and is buried with Martha in Fairview Cemetery, Shantytown, Maries County.
William moved to Missouri with the rest of the family. He enlisted during the Civil War, and held the rank of corporal in the 13th Missouri Cavalry Regiment, Company H. After the war, he returned to Randolph County, Indiana, where his older brother George was. He married Mary Etta Wallace (~1848-1901) in 1869. Known children:
George W. (21 Apr 1870-1879)
Maud Estella (1 Jul 1874-1 Apr 1912) — m. Cary T. Heavlin on 13 Jun 1894
Clyde Oral (4 Sep 1879-10 Jan 1973) — m. Lenna B. Reed on 9 May 1906
The 1900 census noted they had two living children, so if there were others born after Clyde, they didn’t survive. Mary died in 1901. In 1905, William married Sarah Elizabeth Pitts Hoblet (1851-1912). In 1907, he married widow Emma Lydia Boltz Knight (1858-1920) from Pennsylvania, whose mother had the fantastic maiden name Schreckengost. William died in 1918. He is buried in Fountain Park Cemetery, Winchester, Randolph County, Indiana.
James, as noted, died young.
Mary has her own entry in the family tree.
Samuel, age 19, was living with his sister Mary and her husband in the 1870 census for Union Township, Webster County, Missouri. In the 1870s, he married someone named Sarah J. (~1847-????) from Tennessee. By the 1880 census, he and Sarah were living in Miller, Maries County, Missouri, the same town as his father, and next door to Sarah Jane Kelley Mitchell, his brother-in-law Lewis’s sister. He and his wife Sarah had two children:
G. W. (boy) (1877-????)
Nancy A. (1879-????)
Sarah’s son William Franklin (7, born in Arkansas) was also living with the family in 1880. Can’t trace any of them after that.
Maggie, named for her late aunt Margaret Davis, sometimes claimed to be born in Missouri rather than Indiana. In 1880, she was staying with her married half-brother George in Monroe Township, Randolph County, Indiana. She married Indiana farmer George Riley Spillers (Mar 1856-27 Mar 1928) on 1 Nov 1884, and they remained in Monroe Township. George came with a son, Ernest, from a previous marriage, but he and Maggie had no children together.
After George died in 1928, Maggie lived with her stepson Ernest. Maggie died in 1947, and is buried with George in Woodlawn Cemetery, Maxville, Randolph County, Indiana.
