I have heard the name of Jean-Marie Motice as an ancestor for many years, but have never been able to pin down who he is. I had thought he might be the father of Peter, but there is evidence that Jean-Marie was alive in 1783 which conflicts with other informal family histories about Peter's father.
But I have recently uncovered a letter sent to my father from Lynn G. Mottice of Mentor, OH in 1982 that fills in some blanks. Here are relevant excerpts from that letter:
"In the 1700s and early 1800s our name was spelled 'Motice', which you stated in your letter. Peter Mottice had a brother Jean-Marie Motice who fought with the Count de Rochambeau's compagnie de Chasseurs, de Baudre Capitaine. Jean Motice was born on the Anjou-Normandy border and lived in the canton of Isle de France, and left for America from Brest. Jean Motice later became John Mottice. The Mottices came to Ohio as French Protestants. I learned of the above while in France on business."
This story fits in with other "facts" we have about the early Mottices. The combat records we have for Jean-Marie indicate his discharge in 1783, and this makes him an older brother of Peter who was not born until 1772.
Another very tenuous thread that will need much more research is the presence of a John Motes in Northumberland County, PA in 1790. This John Motes was discovered during a genealogical search for Mottices in PA by the Lancaster Mennonite Historical Society.
