Hi Rosie99:
I know Elizabeth Shortland (nee Wright/Right) was my nth-great aunt. She was mentioned in her sister's will and her mother's will but that's it. Her sister, Susan Turner, died in St. Neots in 1735, and her other sister, Barbara King, died in St. Neots in 1753. Since the Shortland's don't seem to be in FreeREG or FamilySearch, I think they might also have been in St. Neots -- since their records don't seem to be included in either database.
I guess I was wondering if someone could have a look in the St. Neots registers for them.
