I have records back for Joseph McLain stating his parents were from Kentucky, but not their names. The oral tradition passed down from my grandfather is that Joseph was orphaned, separated from his siblings and sent to live with relatives. I did the DNA test and it came back with me having relations to the Davis clan through Ignatius' blood line, so I am pretty certain that the statement above is valid. 1850 census shows Joseph McLain living with the Davis family and his place of birth was listed as Missouri. Hope this is helpful.
