He also mentions Fontaine a French Huguenot based in a Maritime enterprise in Berehaven he preached and most of the Protestants attended out of curiosity.   Among the Berehaven colony of about 13 families was the ancestor of Davy Crockett.

In the Bandon Genealogy site there is a reference to  Quaker families from Skibbereen with the Massey and Houlden families mentioned.
