Thanks for that posting Terry. It helped to tie up a loose end for me that is many years old. Joseph Cree of Bolsover DBY married a Mary as his thrid wife and she gave her birth place as Sth Petherton in the 1881 Census. I traced their marriage to Cardiff (FreeBMD) which gave me her surname as Pook. Now I have her birth and baptism record, with parents' details, as she was your Harriot's sister Sarah Pook.
