Hi Geoff
The only parents I have found for William Thorne is a possible match is Rodger and Mary Thorne. William later married a Elizabeth? and lived in London with his wife and two daughters.
Mary and Edward Davey had five known children, Charles, Issac, Henry, Mary Ann and Elis. There is also a daughter born to Mary after the death of Edward Davey Anabella (father unknown).
I have a bit on James Beadon Davey, he certainly got himself in a bit of bother in NZ.
