T.K. Is Tillman Kimsey Seago. He was the founder of Seagoville Texas and there is further information on the town website: http://www.seagoville.us/about.html# . T.K. was the son of Isaac L and Sarah Lucinda Garrett Seago from Cherokee County, Georgia. Tillman and his wife Matilda Davenport had 8 children http://homepages.rootsweb.ancestry.com/~lynn/family/f_5bc.html#5 . Among those was Tillman Benton. He was the grandfather of my father-in-law. I have seen his first name spelled Tilghman.

If I remember correctly Isaac Seago fought and died of illness in the Mexican War.
