Coming back to this after a 15 year break.
I got as far as William Richardson marrying Mary Ann Alder December 17th 1864 / Ashmansworth.
William's father was also a William but I can't find a reference for both together.
Kingsclere, Highclere, Crux Easton, Fosbury, Shalbourne, maybe Hungerford and Great Bedwyn all feature so the Richardsons don't appear to have moved very far in 160+ years.
I was adopted in 1954 and live 300 miles away from the area so can't really go carry out more in depth local research.
In 1851 I have a young William (dob 1841) as living with siblings Thomas & Frederic (and others) in his grandfather's house (RG No. HO107, piece 1686, Folio 153, P.13) - no positive parent listed. This may be a false lead.
I have obtained birth certificates for several other likely candidates but finding the 2 Williams together in the 1840's I can't locate.
Could someone help me out please?
