Thanks, Donna!
I think you have the complicated family pretty well sorted out.

I have one difference from your info. You have "Mary Lawson ch 12 Dec 1813 Ballaugh". I couldn't find a bapt for her with parents Chs Lawson & Mary Gelling except for 26 April 1808 Ballaugh. That was on the IGI, extracted record. Do you know where your date came from?

According to the IGI they married 11 April 1807 Ballaugh (same as yours).
