Thanks for all the information. The FHS are doing a name search in the marriage database for ROGEST, so I'll wait to see what turns up.
I notice that there is another marriage recorded for a Thomas Buckland in Burnham:
Banns
15 July 1820
BUCKLAND Thomas x, bach otp
LOTHEN Hannah, spin otp
Witnesses: John Rance, Mary Austen, Maria Winter
I had Jane Neild as his first wife (marriage 1815), but maybe Hannah was his first wife.
There were obviously 2 Thomas Bucklands around in Burnham at the time, because for both these marriages, Thomas is listed as a bachelor.
I'm particularly interested in Thomas (1785-1876), christened Bucklin, as he is a direct descendant. My mum is a Buckland from Beaconsfield. I've traced her family back to Thomas's father, Richard Bucklin and his wife Mary (see post 13 July). Their children were variously christened Bucklin and Bucklan.
This is where I am completely stuck. I originally had this Richard and Mary as the descendants of a Marmaduke Buckland (1655) whose family come from the Wexham and Stoke Poges areas, but I was mistaken. This branch of the family features a lot of Marmadukes. One of them shot himself in 1730! I'm still hoping that there is a connection somewhere, as they seem to be an interesting lot - and a lot easier to trace!
