Hi Tricia
The honest answer is that I dont know.
I have been doing my genealogy with my mother, we started about 25 years ago but I mostly concentrated on my father's line while she concentrated on her own line. Of course I was as interested in her research as I was in mine as her ancestors are also mine, but it does mean that I dont know precisely which records have been checked.
I do know that she has spent weeks over the years travelling to different record offices and libraries and dedicating herself to the search. It seems logical that she would have checked but then again, if I am totally honest, we both of us have probably concentrated much more on births and marriages than deaths, so it is possible that she has not looked. I know I have not looked.
I dont think we are alone in this, the Mormons for instance have not indexed anything like as many burial registers as they have baptisms or weddings.
I have a vague recollection that my mother thought that the family might have moved to Birmingham, I dont know why, I am not aware that we have any evidence to that effect, but you will understand that I dont want to ask her and draw attention to my quest as it is meant to be a surprise for her birthday.
I am sorry if I sound so vague and pathetic, all I can tell you is that we did the research about 23 years ago, hit a brick wall, waited for the invention of the internet in the hope it would help, it never has and so we have not moved forward in knowing what happened to Matthew, Elizabeth or any of their children, other than our John.
But Aston is a part of Birmingham so it could be helpful if I do get the certificates and confirm whether the Ann and Elizabeth you have found are the
right ones.
We know who their parents were and we know who their children were but we dont know about them themselves and that is what Mum has always needed to know, that is her area of concern, so that is what I want to sort out!
