Hi John,
Firstly, apologies for jumping on your post without any information about your grandmother.
I could be barking up the wrong tree completely but believe we are possibly related. My great great grandmother would have been Minnie Chipperfield. She married a cater and I believe was disowned from the chipperfield family.
My grandfather was Richard cater who would have been Minnie’s grandson, making Minnie a great grandparent to my father. I believe you would be related to Minnie in the exact same way? I’d love to chat further and put any information we both have, together.
Kind regards, Leigh-ann Cater.
