Hello
I have only just begin the journey of finding out about the ancestors, so unfortunately can not offer any new info regarding Edward Ashwin's life. As I continue my investigations I will of course pass on any novelties.
And no, I am not at all aware of the letter you talk of, though I would dearly love to see a copy.
At this stage, I am looking into trying to trace descendants of Martin Richard here in New Zealand and, being somewhat of an historian, I am researching the history of Saxon immigration into Great Britain. It appears that the area near what was later called Bretfortin, was invaded by a Saxon King called Aescwine of Wessex in the second half of the 7th century. Given that apples generally don't fall far from the tree, it only took a brief online search of the UK telephone directory to ascertain that Ashwin is an unusual surname, and virtually all Ashwins in the UK live in the counties surrounding Bretfortin.
Martin Richard was very definitely an unusual man. If you have any info about the family you could pass on to me, I would very much appreciate it.
