Hi Again.
I think if you look at the 1841 Census as I mentioned above.
Mary was not born in County, therefore there did not have
to be a second marriage, unless I am in-correct which I can easily be.

There are certainly no burials in Northants C of E's for a Mary/Mary Ann
maybe clarification may be made for you.
I thought they were going to run into your Piddington ones.

I wonder if Penholder has the same line.
