Hi Sylvia,
If you go to the
www.ayrshire-roots.com site you will see there is a page telling you how you can obtain the information and a page breaking down the film numbers telling you what/when parish they covered.
ie film # 1936793-2 covers
Beith for Dec 1888 - Jan 1896
so it does not appear she is the Matilda you are interested in.
