I'm a Tousley descendant too and have three questions, looking for any help

Who are the parents of Joseph Towsley b abt 1763 (m Rebecca Read) d Canada? I have seen two variations, either Gideon Towsley (m Lucy Olds) or his brother John Towsley (m Reliance Leavitt). Is there any clear evidence?

Did the John Towsley who married Reliance Leavitt also marry Sarah Benton? if not. who was he?

Who is the father of Alanson Towsley of Oxford County Ontario? possible candidates - Arial Towsley, Sikes Towsley
