May have married Demonis Bledsoe, 7 Jun 1808, Lebanon, Wilson Co TN. Possibly died circa 1811. Said to have had one son also named William.

Ken Bowen webpage lists two marriages for William - I believe these were two different Williams - one may be a son of Enos, but which is which?
spouse: Wilson, Mary (*1782 - )
----------child: Adamson, William (1808 - )
----------child: Adamson, Elizabeth (1809 - )
spouse: Bledsoe, Demaris (*1783 - )
----------child: Adamson, John (1809 - )
----------child: Adamson, Delilah (1810 - )

There are marriages in Wilson Co, the same place where William married Demaris and his brother Elijah married Susannah Hathway:
John Adamson married Polly David, 3 Dec 1825
Delilah Adamson married Thomas Belcher, 27 Apr 1827
