I am slightly surprised to find you state this board is only for the County of Somerset, as the link at the top clearly shows thus;
Message Boards > Surnames > Somerset > Jane SOMERSET
So taking that into account you'll appreciate why I posted here.
Yes I also realise that 'of the parish' can sometimes only mean that the person living there at the time of marriage, but I have not traced any christening there or in the surrounding area that might be her at this moment in time.
Thus I was posting here in case anyone had happened to have looked into the Somerset lines in this area.
If this is now only a county board rather than a surname board, you might want to ask ancestry to change the linking for it, as it is certainly not listed under the county section.
