In my mother's second book, she included a good deal of material from a lady named Maydee Brite Crawford from Ekron, Kentucky. This was not my mom's research, but she seemed to feel that it was, by and large, good info. This included Dennis Brite...father, son, and grandson with the same name. Let me quote Ms. Crawford's material about the the 3 of them.
"On Sept. 23, 1812, Dennis Brite, son of Hopkins and Nancy Brite, m.Mary "Polly" Ford, b. ca 1797; daughter of Elisha Ford. Dennis d. before 1850 probably in Hancock Co., Kentucky. Mary is listed with their children on the 1850 census of Ohio Co."
"Dennis Brite, b. ca 1832; married Ada ___. Children: (1) William Brite, b. ca 1856.(2) Jonas Brite, b. ca 1859.(3) Ada Brite, b. ca 1860. Dennis Brite, b. ca 1866.(5) Emma Brite, b. ca 1869."
The father Dennis had a nephew named for him. This was the son of his brother, Hopkins. This Dennis was born about 1829. There is no other info about him. The brothers Dennis and Hopkins were the grandchildren of Albertus and Patience Hopkins Bright.
This is all that I have about Dennis Brite. I have a bit more about the children of Hopkins Sr. and the direct line to the writer's family. Wish I could be of more help.
