Hi
I am Walter Clarke's Granddaughter Allison Weston Voss (nee Clarke) and saw your post concerning Walter's Family. I live in New Zealand where my Father Ellis, mother Dorothy (nee Weston) and brothers Stephen and Mark emigrated in 1956. I believe I can help you.
You will notice the E on my Clarke . Mum always wrote to Grandad with an e in-place.
I have English relatives, who spell their name without an e ...Clark. Few of the Clark(e)s made family trees and when I got interested My Grandmother was old and had limited knowledge of Walter's family. I see Ronald Clark in in your replies I have just had contact with him in the past week for the first time.
My Grandmother definitely was a Marcroft tracking into the Kinder and related families.
I have a website on MyHeritage.com and would be happy to share information with you.
Never used this website before as I have joined just so we could help you.
Not sure how to do that privately???
