Hi All
Sam has sent me the cert ,and it is indeed what we had suspected.
Mothers name is Mary Blanche Clarke but she signs B Clarke(maybe she never used the Mary bit?) and again as thought ,no fathers name on the cert.
I am hoping to attach a section of it here,so we can all see what a flamboyant writer the registrar was and how he finishes each word off with a flourish that makes it look like it ends with a letter r

Blanche(r) CLarke(r) and even Quadrant(r)

Well done Liz,so Sam is really motoring now,if you get that marriage cert Sam,we'll be able to help you find all about Mary Blanche CLARKE.
