Buchanan Stewart (M) Jean Primrose 1794

I descend from William Stewart (ca.1814) and Jean Fleming (ca. 1816) of Paisley, Renfrewshire, Scotland. Married 17 May 1834, in Abby Paisley. No parents mentioned.

I am quite certain that Wm is the son of Buchanan Stewart and Jean Primrose. I'm looking for proof.

Wm and Jean had a daughter named Primrose ( my ggrandmother) born 1841 in Paisley.

Can anyone help me with the connection between Buchanan Stewart, Jean Primrose and William Stewart and Jean Fleming?

I am hoping to hear from someone,
