I am a descendent of Christian Croussore, son of Michael Croussore, who was born in 1750, possibly in Alsace.
The family pioneered Howard County Indiana. I have reason to believe that there is a tombstone for Christian Croussore in the town cemetery in Greencastle Indiana (just east of Kokomo). This tombstone lists the military unit in which Christian Croussore served.
I was told that this referred to his Revolutionary War service, but the date does not fit---Christian was born in 1777.
Possible it is a reference to his father, Michael Croussore, who was born in 1750.
If anyone has this kind of info regarding Christian or Michael Croussore, please email me. Thanks
