Joiner and Hannah Stokes had a daughter Sarah born 9 October 1814 and baptised at Ramsey on 30 October. So she could be the woman who married Benjamin Slote. However, as the marriage took place in 1832, her father's details aren't recorded in the marriage register.
Sarah Slote was buried at Holme on 2 February 1840, aged 27, which would indicate that she was born a little earlier than 1814.
A Sarah Stokes d/o John and Ann Stokes was born 12 October 1812 and baptised 25 October at Ramsey. This couple don't seem to have had any other children baptised at Ramsey.
William and Elizabeth Stokes (mentioned earlier as parents of Jemima), had a daughter named Maria born and baptised at Ramsey in 1808, and one named Sarah in 1809 ( so probably not your Sarah). Just to complicate matters, Elizabeth's maiden name is also Johnson. They married at Ramsey in 1801.
A couple named Thomas and Mary Stokes are baptising children at Ramsey at around the same time. Their address is given as Holme Fen. They had a son named Thomas in 1808. None of the other Stokes families have a Thomas, and only William and Elizabeth have a Maria. (This getting like one of those logic puzzles. Sorry)
Just seen Roger's last post. That would make Sarah d/o John and Ann a good fit.
