I went ahead and merged them. I would prefer the spelling Braithwaite to either of the two which were previously on profiles. I think it is likely that the dates are wrong by decades and that the connection to the Stone family is in error.
If anyone has good sources, let me know and I will fix them. Apparently the best source is: "Generoso Germine Gemmo", which was a Monograph by Lieutenant Colonel Garnett Edward Braithwaite - it is not readily available.
