Hi everybody!
I am sorry to tell you that there's very little chance the Mougey Family could be related to the Bonaparte...
Most of the french Mougeys still live in north east of France (Doubs department) where my grand parents are.
It is still hard to find info about families since documents disapeared (mainly at the French Revolution) but i will try to find more info next time I will go to Crosey.
It is great to find out people all over the world are related...
I will come back to you (hopefully with more info!)
Good Bye Family!
