These are thought to be photos of them but the owners cannot guarantee:
OK, so I am clipping along doing research on Thomas. He is the son of Talamacus and an unknown/unsure mother. According to his head stone, Thomas was born 15 April 1843. Lawrence County Arkansas censuses 1850 though 1900 consistently list birthplace as Missouri and verify that his father has a difficult name to spell ;)
I find a marriage certificate in Randolph County Arkansas of Thomas Whittaker and Melissa A Whittington. You can see below that Randolph County is the county north of Lawrence County and Randolph is on the border with Missouri.
The certificate states they were married 8th day of June 1863, that Thomas Whitker is from Lawrence County Arkansas and is 21 years old, and that Mealisia Ann Whittington is from the Butler County Missouri and is 18 years old. The certificate lists her father, not by name, as doing something regarding her age (can't read it).
They have children in 1866, 1867, 1869, 1871, 1873, 1875, 1876, and 1879.
On the 1870 census "Malissa" is listed as 24 born Tennessee. (there is a Thomas Whittington next door and Talamacus Whittaker two doors down). 1870 - 24 = born 1846.
On the 1880 census "Malessa" is 27 born Missouri. The oldest child is 14 meaning if this Melissa is her mother she was only 13 when she delivered her. We know from the marriage certificate that "Mealisia" was 18 when they were married. 1880 - 27 = born 1853
On the 1900 census "Mallissa A" is 48 and born in Missouri. They also state they have been married 20 years meaning they were married in 1880). 1900 - 48 = born1852
Thomas and his wife have more documented children in 1882, 1883, 1884, 1888, 1889, 1891, 1896.
Long story short - according to other researchers, there's a second marriage for Thomas to Malissa Ann Whittington in Butler County Missouri on 25 Jun 1879. I'm told the first Malissa died and he married her first cousin also named Malissa Ann Whittington.
I found this listing from Butler county Missouri Marriage Records Book C at http://www.usgwarchives.net but I don't have a copy.
