Thanks for that Slowhands- I'd be happier with this family too!! :)
I found the family in 1841, and that states 'y' for Elizabeth being born in the county.

I have son George's birth cert from 1841 and Elizabeth is definitely a Blanch-

Interestingly I have found that there is a member of Norfolk FHS who has a surname interest Blanch from GlS logged on the site. I have sent a message to see if I can find out more. Or maybe they are like me and stumped as to why Yarmouth in 1851!!!! Oh, the twists and turns.................

Sorry Janice, I seem to have hijacked your thread.
