Sir Marmaduke Beckwith born 1687 Aldsborough, Yorkshire England in 1687. He came to Virginia and was married to Elizabeth Brockenborough Dickson, a widow. His parents were Roger and Elizabeth Jennings Beckwith. Roger is son of Edmund and Margaret Barkham Beckwith. Trying to find their relationship to my ancestor Marmaduke Beckwith who married Maudlin Creed and came to Virginia in 1664. Does anyone know Edmund's ancestry.Thanks.Tom.
