This is my group of Adairs. At least we were in Pennsylvania, Delaware, and Maryland in the 1700's. Our earlies documented Adair is Samuel who died in 1773 in Maryland. Family story is that he was the 4th son of Thomas Adair of Pennsylvania and the first born in the Colonies. He is said to have traveled to live with or near his Uncle William Adair of New Castle Delaware. He went to the same church and lived near by. Our Samuel was married to Hannah and left a will in 1773. William also had a son named Samuel who was a Revolutionary War Patriot. OUr Samuel died in 1773, My cousin Douglas Adair has taken the yDNA test on Ancestry.com. We are looking for genetic proof of our connection to the PA/Delaware/Maryland Adairs. Samuel's son Joseph lived in PA, Kentucky, and finally in Jackson County, Missouri. His son Abner John Adair helped to found and lay out Independence, Missouri. Hopefully, someone can helpus. This is our first attempt at DNA testing.
