Well that is great,
The only thing that does not fit, is in his will he mentions his wife as Jane ? The Bland would fit in perfect as latter on the fly boats they operated from Long Buckby and Braunston were called Worster, Stubbs and Bland ! My gt gt Grandfather was born in Worster Wharf yard, Bridge St, Northampton.
They only thing i can think of is perhaps Elizabeth is called Elizabeth Jane ?
So he was married before, I had another look at the will as it 3 pages long ! and does say something about if his sons had of survived perhaps from the 1st marriage ?
The clue is trying Edmund york Abbey married, as we know he married the step daughter Mary, so the christing of Mary to Richard and who ?
