GA.On the 1860 census John is in AL and Robert E. and John M. are in Randolph Co. with Dennis.John and Andrew were born in Ireland.John was with Andrew DeLacy on the 1845 Gadsden FL voter's list and that is where his children were born.Any help to establish the connection with these DeLacy's will be appreciated.
