His death record (linked in the profile) reads:
64. / Nov 7 [1864] / Louis M. Bailey / married / [aged] 76 y 4 m 24 d / suicide by hanging / [place of death] Duxbury / tobaconnist / [place of birth] Nantes, France / [parents] Louis & Emma
So the father seems to be a Louis Bailey/Bailly, not Jean Sylvain. And if the age is exact, date of birth is rather 14 Jun 1788 than 16 Jul 1788.
