Hello Gemini,
I know that you posted this message re:Agnes Hatch a long time ago now, but I've only just come across it in my own family tree research!
You mention that you think that Daniel Parker Hatch's wife may have been Jane Swinyard. Jane Swinyard was my 3x great grandmother, and I don't think that she was married to Daniel, but it is true that an Abigail and a Katherine Hatch were living with Jane and her husband William Henry Swinyard in Faversham, Kent in 1861. According to the census the Hatch sisters' relationship to the head of the household was 'mace', which I'd always assumed was a mistranscription of 'niece', so perhaps Jane was Daniel's sister. If so, that would be a big help to me, as I've never been able to establish Jane Swinyard's maiden name!
I'd be grateful for any confirmation you might have one way or the other.
Best wishes,
RromHughes
