Living in Fitzroy in the 1851/1852 census, and is listed as a farmer, and Roman Catholic. Due to the age difference between him and Adeline (as well as the age of his eldest son), I am suspecting that Adeline was his second marriage.

I have found a Thomas A. Sullivan in the 1831 census for St. Armand, Quebec (Lower Canada), that may be him. If it is, there were 2 male children under 5 years old, Thomas and his wife, and a single male between 21 and 30 (a brother, perhaps?). Thomas is listed as a cabinet maker at the time.

The history book “Kansas Trails” (published in 1910) mentions that Thomas and Adeline lived in New England for about 15 years, before joining re-locating to Fitzroy, where they farmed until 1870. They then joined a colony of twenty bound for Kansas, and came to Kechi, Kansas on June 15, 1870. It also describes Thomas as “an educated man, of fine character, and was prominent in occupying local offices while a resident of Ontario”.

He shows up in the Wichita, Kansas area in the 1870 census, living with his son Charles Edwin (a farmer). He is still shown as a cabinet maker, age 74. It is mentioned in the Kansas Trails book that he followed his son George to Kansas about a year after his son went there, and that he also made some of the coffins used by the pioneers of the area.
