Hi
Thought I would call in the Societe library this morning and I think I have your answers.
Elie Gaudin married Marie Le Bastard (now has the letter "s") 4th Aug 1773 in St Martins.
The baptism of Elie in St Martin is 19th Jul 1741 to Elie and Francoise Nicolle. There were no other Elie baptisms between 1727 and 1756.
There is a baptism in St Martin for Elie Gaudin, son of George Gaudin and Anne de Queteville, 28th Jan 1712(3). There are no earlier Elie baptisms.
Elie Gaudin married Francoise Nicolle of St Saviour at St Saviour's Church, 14th Jun 1738.
George Gaudin of St Martin married Anne de Quettevill (no "e") of St Martin 20th Jan 1702 at Grouville Church.
Now, I have found a large family tree of the Gaudin's that has been donated to the Societe. When I say large, I mean large. There must be over a thousand names hand written on the tree going from 1540 to the 1920's. It's been donated by a lady from Derby. All of the dates I have given you I have checked against this tree.
