No, I don't know of a SWINK/Nash connection. But I've got a Henry O NASH who claims birth in a number of places but most often TN. Do you have a stray Henry lost? He was born about 1820-30's. Married in Tishamingo Co MS in 1853 to Nancy HILL. He may have been in TN on the 1850 census, can't prove it, living with a Tony Sellars. Anything familiar here? Rebecca in Cajun Country
