Hi Deb
Rootschat forum is a great place to find details on ones forebears; I personally rate it above Ancestry simple because of its many many friendly and knowledgeable members who like nothing better than to help others solve their family history problems.
I have looked for a marriage for Thomas Gannon = Adeline and the only one I can find is this one: Marriages Dec 1887 Thomas GANNON & Adeline Delfine Hughes, Birmingham 6d 65
Using their details I checked for a birth (Winifred) and the only birth I can locate for a Winifred born 18 Feb 1888 is this one:
Winifrida Gannon
Birth Date: 18 Feb 1888
Christening Date: 05 Apr 1888
Christening Place: Birmingham, Warwick, England
Father's Name: Thomae Gannon
Mother's Name: Annae Mariae Hughes Gannon
Could this be your grandmother I wonder? (note transcribed as read)
PS: Say hello to Brian, played skittles with him many years ago.
