Dear r973g:
Thank you very much for posting this data and for taking the trouble to look them up.
i knew absolutely nothing about John ROACH's family, therefore, I appreciate the marriage(s) info.
When you say "other marriages of females that appear to be siblings of John later" do you mean there are other marriage on the PRs, other than those which you posted (Robert 1851
Hester 1843
Mary 1842
Ray ) ?
Kind regards
Javajune
