Ok I am widening the net a bit ....
We've established that Robert Allen is son of John Allen & Susannah Bracegirdel. I am pretty sure John is son of Matthew Allen of Alconbury, who married Bridget Woodley of Buckden, on Dec 12 1780.
... and I'm sure that these had another son William chr 25 June 1798.
I'm now looking for a marriage of William to a Maria ?
They had George in 1820, James 1822 & William 1825
Can someone please find the marriage of William & Maria
Thanks John
