    owned by Willam Bay, deceased.  Though no father is stated, evidence
    that they are children of Hugh [Sr.] includes that Robert stated he
    was born on "Seder" [Cedar] Creek in Virginia in 1760. [see #15]  The
    only Bay family members of which there are records of living on Cedar
    Creek at that time were Hugh Bay and William Bay. [see #2b, among other
    land records.] William died with no children. [see #9]  While Thomas
    Bay (brother to Hugh and William) did have a son Robert Bay, he is not
    the Robert of record #15. By elimination, the conclusion is that these
    "brothers and sisters" were children of Hugh Bay.  The various heirs
    either acknowldeged the deed or witnesses testified to their signing
    over the next several years.
