Thank you so much for your speedy Cavill lookup!
They seem to check out but I will need to look at it all more closely tonight. I'm delighted to see Miranda there because my late mother's grandmother Sarah (who didn't emigrate!) used to talk about "Aunt Miranda who went to America" and we've always been intrigued about that. But now it seems odd that she put it that way given that Sarah's parents and seemingly several other siblings went to America too!
BTW, I see most of your surname interests are in Sussex. I now live in Chichester, county town of West Sussex (Shoreham is at the other end of W Sx, Rye is in East Sussex). Our county record office is in town here so if I can be of any assistance, drop me a PM. Be warned that I'm a total newcomer to all this ...
I'm also looking at surname Batty (from my father's side) in the Skipton/Ilkley area of Yorkshire, or would be if I could tear myself away from the Cavills ...
