Jean François passed away April 26, 1873. The tombstone reads, "Priez pour son âme," which means "Pray for his soul" in French.
Jean François' birth record is below. He was born in the town of Herbeuville in the Meuse department of northeastern France. His parents were Nicolas Aubry and Anne Catherine Colnard. The birth record indicates he was born in 1802, which is fairly consistent with the ages listed on his U.S. census schedules. (Even if you CAN read French, don't try to find '1802' in the record below; the date is listed using the French Republican Calendar, and needs to be 'translated' to the Gregorian calendar to figure out that it is indeed 1802.) The tombstone lists his age at death at 66 years, and I believe that the stone is wrong in this case.
