Ellen, I have a Gideon Floyd b. abt. 1822 that married Rhoda Chastain Taylor. Gideon supposedly had a sister named Levinia that married John N. Tinsley abt. 1835 in Edmonson Co., Ky. Gideon and family was listed as HH#94 Dist. #1 Warren Co., Ky. census. Also listed was HH#94 John N. Tinsley and his wife (only initial was a "L" age 32). I was wondering if maybe this was your Gideon Floyd also.
