In regards to Asa Davis, I have that name in my history file. But he is the son of Squire Davis who was born in 1826 in Wayne Co., IN and his wife Mary Haworth b.1834 in Winchester, In. Squire was the son of Samuel and Nancy Davis who moved to Randolph County, IN in 1831 (I don't know where from). Perhaps your Asa could be the brother of Squire. I do have other Davis families in my file, but they originate in England, through North Carolina, to Pennsylvania, to Virginia to Wayne County, Indiana. Eventually, they lived in the Darke Co., OH area.
