Hi Gerald - I found this post (as I've just joined I am unable to PM just yet).
I am able to provide all the information you need on your Great Aunt Elizabeth McGill as she is my GGrandmother.
Elizabeth actually got married before she moved to Scotland. 22/05/1897 to my GGrandfather James McLaughlin. Married at Limavady Roman Catholic Church, Drumachose, Londonderry.
I look forward to sharing much more information with you!
