I enjoyed reading your history of the Gretteaux family.
I am descended from Jean George Gretteaux's daughter, Susanna Catherine. She married John Peter Rudolph, a Palatine immigrant who came on the Pearl in 1752. They were married April 6, 1776 and had five children, including my GGGG grandfather Alexander Rudolph, who moved to Liscombe in Guysborough County.
Please send me an email. I would like to share info on our ancestors.
