He has no direct descendants, true, but there are many of us descendend from his relatives. I am a direct descendant of an uncle of Joseph Hewes the signer.
Aaron's brother, Joseph Hewes, married the sister of Providence Worth. There is a long line of Heweses, some settling around Balimore MD in the 1800's. My great-grandfather, Meyer Lewin Hewes, was married in Baltimore and moved to Hartford, CT. His son was Thomas Hewes, my grandfather. His son was Charles Hewes, my father.
