You are right about lots of Braces.Ihave seen a number of Trees but am not convinced that the early Braces are right,,thinking that there appears to be 2 couples with the same names haveing kids at the same time. I have noted that I would like to see the Parish Recors myself. I do not have your line in my lot...but thats not to say with info from the Parish Records they would not meet up in the future.
Best UK place for research is Genes Reunited, lots of Brace researchers /descendents on there.
