I have now looked through your old posts. You appear to have traced back to a Robert Heritage, b 1812 Holborn, who is likely to be one of the children of Thomas and Maria Heritage. Their other children are:
Edward/Edmond (1810); Thomas (1813 & 1807); Maria Ann (1809) and Deborah (1815).
Everything so far is linked to the Holborn area. Is this correct?
One small piece of evidence in favour of the Warwickshire connection is that Samuel (b1792) is living with his wife and family in Hackney, and has clearly been there for at least 13 years.
