My ggg grandmother was Sarah Penfold, born 1784 died 1857. She married Henry Eggleton in 1805 in Epsom, Surrey. I have microfiche for some of the BMD's and census of the early 1800's for Epsom and Ewell but can't find the ones that are being researched by the people in these emails. I also visited Woking record center and listed all the baptisms for Penfolds in Epsom.
Hope we have a connection - I'm sure we do we are all in the same area. Let me know if you want me to look on my records of Penfolds for other names.
