Hi all,
Thank you for your replies and information.
I never realised the index contained multiple entries due to spelling variations of names, so I appreciate your guidance.
Further thanks to Brentor boy, Girl Guide & Galium.
I was able to trace Catherine's marriage to "William Henry Bryant", who is my 2x Great Grandfather, but as others have discovered there appears to be no birth registration or baptism for Catherine.
In an attempt to square the circle, I did try to trace Catherine's father George Elmer (taken from marriage certificate), however there were no obvious results. I was hoping to see Catherine (or Katie) as one of his children on a census.
After 10 hours of researching, I've decided to save the information I could find based on spelling variations etc. and come back to it another time. I am thinking of adding all the discovered data to a spreadsheet and creating a truth table based on known information in the hope I have a eureka moment.
I am new to genealogy, so unsure if others adopt this approach, however I create in-depth spreadsheets for my work and believe I can create a formula that will narrow the field of possibilities.
I did see the census entry that Galium mentioned of a Catherine Elmer - daughter - age 5 in King Lynn.
If this is my Catherine, she seemed to move around the Country as she was born in London, possibly moved to Kings Lynn, was married in Gateshead and then lived and died in Portsmouth.
She comes across as an interesting lady, just wish she was easier to trace.
Thanks again for your help and advice, it is greatly appreciated.
Steve
