Thank you so very much, Bryant.
Despite repeatedly scouring for them, I had indeed missed these two examples.
I cannot think how I missed the latter, as I have searched on Robins, Robin, etc, etc.
Cornelius, however, I missed because I had thought that Robin'SON' was not used until much later in the family history.
You have taught me an extremely valuable lesson - NOT to assume anything and to consider everything.
I shall digest the details you have so kindly unearthed for me and see what new avenues they might open!
Again, I sincerely thank you...
..... Steven.
P.S. - I cannot help but wonder what, if any, connections you might have to the above.
I wonder because Bryant is a branch of my family (connected via Wileman through to my mother).
