Hi Heather
i'm sure we've been in contact before. did you have an email address starting fredders? if so i still have an email i tried to send. if not it may be of interest anyway. i agree i think your John brine bn 1773 is the same John Brine born to John and Dorothy Symonds on the 4 July 1773 although i've not added it to by tree yet. i also think we go back to Tolpuddle. i have a copy of a Tolpuddle will from which i base my assumtions. the details are in my email if you are interested.
regards Austin
