Hessu/Myfi:
Hessu, I haven't forgotten about my email. Just short of time at the moment - but will get around to it. Busy changing country for the winter.
I don't know where I found this snippet of info. but as Burstwick is near York and a suburb of Hull, that William may be related to the following post by -
Eric Abbey in reply to Henry W Abbey from Hull, England by Theresa Orr.
"So far as I am aware, there are 2 branches of Abbey in Hull, the Henry W that you seek is probably not an immediate relation of mine but I would be very interested to know if you are aware what the W is for. My grandfather was Harry Waite Abbey (1879 - 1959). He was born in Hull and lived there all his life. His father John, was originally from York in northern England so it is likely that the two families are separate".
I'm guessing that he doesn't live in the UK and know the Geography.
He goes on -
"Out of interest there is a large window in the Holy Trinity Church in old town Hull which is dedicated to the Abbey family. There is also a large burial plot in a now disused cemetery on Spring Bank West just north of the centre of Hull. This burial plot is, I think, that of the Abbey family commemorated in the Holy Trinity window.
If you know what the W stands for, it may link the two families"
I think his two families probably are linked, purely because of the closeness of the 2 towns.
I'm not sure if this helps us in any way but I thought it might be a snippet you didn't have.
