Hi, Mike, and welcome to Rootschat!
This is most exciting, and if you reply to my own response here I believe that with your two postings on this website we should be able to communicate further by PM (Personal Message) on here.
Remarkably, we are (distantly) related, with common ancestors in Henry Pakeman GURNER (1796-1880) and Mary Ann WHITE (b.1795 in Pembroke, Wales, died 1872 and buried in Ickleton, Cambridgeshire, as was her husband Henry Pakeman); they are my gt-gt-gt-grandparents They both lived in London from their marriage in 1821 until the mid-1860's when he retired as a tea dealer and they both came to live in the family home of the GURNER's in Ickleton. This was in the family ownership from the early 17thC until the 1970's, is still standing, and is in good hands even yet...
Nesta was one of Henry and Mary's gt-grandchildren, through their daughter Mary Ann (b.1830), and one of her sons (I've forgotten which one, at the moment!). I have a copy of her birth certificate of 1893, and the cousin I spoke about at the start of this thread has many photographs of Nesta's KERSHAW family as she grew up.
If you're interested at all in our common family history, I can let you have all kinds of other details. Curiously, the cousin in England is as interested as I am in all this genealogy, whereas her sister in Canada (moved there in the 1970's), who lives not far from your family, is much less keen...
Hope to hear from you again soon,
