Hello Girl Guide and Gibel
Girl Guide
Their daughter Sarah Seamark married my 4 x great-grandfather Thomas Fitzgerald, one son was named John Storer Fitzgerald and a daughter named Sarah Seamark Fitzgerald they were all also baptised @ Saint James, Westminster.

I have seen these baptisms, but to the best of my knowledge I am not aware of any links to Northamptonshire, needless to say it is not impossible!
I am aware of Lydia death in 1762, and I do not know what his occupation was.
I do have a Jane Seamark on my ever increasing to do list. I will research her details as soon as I can.
Thank you both or your replies.
