I also have in my records that an Abraham Fleet and his wife, Eliza J....were on the Dickson Co.,MO. census. - I have another record on them that shows they were both buried in Tyrone Cemetery, NY....where they were from.
This still puzzles me.
I am also aware of an Abraham Fleet who came from NJ/NY to Jasper Co.,MO., and bought "the Fleet farm". This Abraham Fleet (along with his son George W. Fleet) are buried in Jasper Co., MO.
