Davy Crocket’s ancestor James Crockett born c 1674 (may be later) was the child of one of the 13 Huguenots who worked with James Fontaine in a short lived fishing enterprise around the late 17th century to the early 1700s. He was Louise de Sax Crocketagne (Anglicised to Crockett) mother Antoine. The fishery was in the Castletown/Dursey area.
Interestingly Fontaine (James Fountain 1702) and his son James Fountaine Junior (1710) were appointed Justices of the Peace for Co. Cork suggesting that they were well connected
