Send a message to the person who requested a photo of the grave monument of Thomas Hester with the following comment:
I am hoping that Thomas HESTER and his wife Hannah Rose HESTER are my ancestors. Their daughter, Ann Simpson GILBERT, also being my ancestor. The dates appear to match, as Ann died in 1840 in Aylesbury but I note that there are no dates for William GILBERT. If this is the right William, he immigrated to South Australia and died there. The family were non-conformists.
