My mother is a Ewart,and I have attempted to take up the research that one of her Ewart aunts did many years ago. She established through records that James Ewart came from Ireland with an infant son, David, my line, who was either born in Ireland or perhaps at sea. James settled in Washington Co., PA in the late 1700's. David married and moved to Butler Co, OH, and then to Indiana where he died leaving a wife and minor children. I took the name to the library in Dallas where the director of genealogy is quite a prominent writer and researcher, and of German descent. He took one look at the name and declared that it was German. I have found it in German records spelled Ewert, rather than Ewart. So perhaps they did come from that area originally. I don't know if there is a Ewart DNA project, but I do still have some male Ewart cousins around. I've also been told that Ewarts came originally from Scotland, and on American census records found them listed as Hewitt and told sometimes spelled Youart and probably other variations.
