Recently I have found two DNA matches via ThruLines who are descended from a Ralph Hercomb and a William Henry Fisher Hercomb respectively. My own research has confirmed that Ralph and William were the sons of Thomas Hercomb, a tailor of Uley in Gloucestershire.
So now I’m thinking perhaps my George Hercomb may have used another name, hence why I can’t find his baptism or census records prior to 1861.
The sons of Thomas Hercomb, tailor of Uley, and his wife Elizabeth Fisher were:
Henry 1805
Thomas 1807
Elijah 1808
William Henry Fisher 1813
Ralph 1817
