With the help of Leo Adair and others, I now have strong indications that my Joseph Adair b. 1766 in Cecil County, Maryland, was the son of Samuel Adair and Hannah _____ of New Castle Delaware. There is also strong evidence that Samuel was the brother of John Adair and the son of William Adair b. about 1706. I would enjoy hearing from any members of this line of Adairs. Thank you EVERYONE for your help with this novice geneologist.
