Send a message to the person who requested a photo of the grave monument of Hannah Eggleton with the following comment:
The Princes Risborough Upper Baptist Chapel Register has Joseph Eggleton's birth date as 27 Nov 1814 and his stated age in the censuses of 1851, '61 and '71 agrees within 1 year. Might be worth checking the transcription on the Headstone.I am prepared to help, but not sure I can at a distance of 12,000 miles
