Thanks joger and Zefiro.
This was back in Notre Dame registers.
Interesting that both Jean, and his son Pierre, use the nom de guerre La garenne.
I wonder how he got to stay in Montreul sur Mer?
There are batisms for nearly 10 children from 1655 to 1673, and Jean, the father here, dying in 1687.
I haven't found anywhere that says he is an 'invalide', as I have in the past here in Montreuil sur Mer, just 'soldat' on some of the children's baptisms.
So it doesn't sound as if he was invalided out to M sur M.
Perhaps he just had a posting that allowed him to stay in the town, rather than move on when his regiment did.
Interesting.
