Did you see ELL's post about the birth record of a Thomas Willis born to a Mary A (maiden name Peterson)? in Madison County, which is Richmond, KY.
From that this Thomas married a Betty Coffey in 1975, from that union I see 3 children born in Madison County also, in the years 1976, 1978, and 1989, so the youngest it appears is around the same age as you.

You must remember, we only have information on a Thomas Willis BORN in Kentucky, if he was born elsewhere and moved to the Jefferson County/Louisville area or elsewhere in the state, we would not know if in fact this is the True Thomas Willis you are seeking...but it is a start.
