Have your brought your Marcum family forward? My grandmother was Lucy Green Marcum married James Thomas Willett. She was born 4/17/1870 and died 5/12/1934.
Haven't confirmed that George W MARCUM (b1/1830)and Mary Jane GREEN (b 2/5/1836).
Do you have a George W in your descendants? They were in Green Co to the best of my knowledge although Lucy was born in Hardin or LaRue Co. (Upton straddles both I'm told)

Any clues or help will be appreciated.
