Nancy Ann Shuler - Shuler - Wingard marriage

Is there any source for the union of John Adam Wingard and Nancy Ann Shuler?

I have a reference that Wingard's wife -- and mother of his son Robert Morris Wingard -- was Anna Kleckley. I can find no source or record that ties Shuler to Wingard. I do find sources that she might have been a Dreher, and wife of Thomas Shuler.
