In adding to Pierre Delon's French family in Saulxures, Bas-Rhin, Alsace, France that my Peter Dillow in Virginia matches in DNA testing with consist of marriage, baptism,and godparents in records. Pierre's parents are Jean Delon and Benitte Martin.
Some of the names in the records are :
Nicholas Le Boube, Nicholas Delon, Marguerite Benoit, Michael Benoit, Nicholas Georgeon, Barbe Chrestian, Christopher Charpantier, Marie Poirelle, Odile Dieudonne, Marie Ceublair, Jean Lurhans.
On 15 Sept 1749, Nicholas Delon arrived in Philadelphia on the ship Phoenix. He came the same route as Pierre did on the ship Princess Augusta in 1736 and settled in the same areas of Pennsylvania.
That is as far as I have been able to get more info on families connected with Pierre Delon in France.
