Mary Jenkins (Neill) - Proof of Marriage and Children

I connect to the Jenkins line in two places and the Matherly line.
As far as I know, there were records firmly demonstrating that Joel married her.
Mary Ann " Polly" Jenkins Matherly mother was Sarah Eliszabeth Woods Jenkins.
I agree with the other wife. It is well documented. Bobby Anderson spent years researching these families and wrote and published about them. Can you please provide documentation? Thank you
