I'm not sure if this is your Wailes, but the information that I have lists a Nehemiah Wailes, born about 1625. He was born in Saint John, Newcastle Upon tyne, Northumberland, England. He married Elizabeth Saughfeld, who was born about 1630. Together they had Benjamin Wailes, about 1680, in Somerset County, Maryland. I'm not sure if he had any more children. Benjamin married Elizabeth Covington (born 1681, Stepney Parish, Somerset Co., MD) 1710 in Prince George's Co., most likely in Wayne Township. They died within two months of each other. Ben on Feb. 14, 1729 (Somerset Co.), and Elizabeth Apr. 7, 1729 (Prince George's Co.)I have more information, and if you need more you can e-mail me. I hope this helps.
