Hi no we still do not know her maiden name,the records are quiet clear that the name is Buchanan but you must remember that lot's of people could not read or write in the time scale you are looking at also the regional accent did not help also the clergy nearly always came from upper middle class famlies and would have lived many miles from the parish so would have no idea just how the name should be spelt,still nothing like getting another two children to put into the tree,will try for the marriage next time,I did look up Boyds which is a index of marriages in Essex and could find no Bohannan listed but the index is by no means complete,so who knows waht I will find
Best Regards
