Can't help with WILLIAM CARROLL, but some info from Maryland State Archives descriptions of microfilm: CHARLES CARROLL the Settler b:1660,arrived MD 1-10-1688, d:1720.His son was: CHARLES CARROLL of Annapolis b:1702,d:1782. He married Elizabeth Brooke and their son was: CHARLES CARROLL of Carrollton b:19-9-1737, d:14-11-1737. He married Mary Darnall. Do you have a David A Carroll of Baltimore, b:1812 and his daughter Fannie A Carroll b: Dec 1838 who married John T Timanus?I have the names etc of their children if needed. Thanks and good luck.
