Thank you SandraAust
Mmmmm - the David born c1798 sort of ties in with a David that I have found born c1799 & had partly attributed to William Green & Sarah (Philpott). The earliest birth I have found that I can positively attribute to William & Sarah is Robert who was buried in 1812 (Suffolk Burial Index) - infant son of William Green & Sarah (Philpott).
I can positively link a David Green c1799 I have found as being the brother of Jeremiah, a later child of William & Sarah, but that does not prove they had the same mother. It had crossed my mind William may have been married before Sarah, a sister is always a possibility, & of course there is a chance they may be nothing to do with my Philpot's.
Could not find the entries you are talking about on familysearch - perhaps something happens when the website is turned upside down??? Could you possibly send me a link?
thank you for your help
