Hiya Damian,
I have little on the Bettisons at the moment as I have concentrated on the larger families (the descendants of these have come forwards first) the smaller families seem to be slower at coming forwards, I do have one other Bettison contact who has sent information, I would dearly welcome more as I would like to release information on all the revolution families for the revolution bi-centenary in 2017, I do know that almost all of the revolution families were related, including the Bettisons
We are in the process of organising a massive year long Bi-centenary event which will link Pentrich and Australia in a massive celebration
