Not sure where you got 1782 from. His baptismal, marriage and death record (which I'm attaching) all show he was born in 1778. His baptismal record is in Latin. One of the witnesses on his death record was his brother Joseph.
I went to GeneaNet to see if he's in anyone's tree. You can search and look at trees without subscribing. I found two trees with him in it.
These are the two trees:https://gw.geneanet.org/titi1977?n=boehler&oc=3&p=mi...https://gw.geneanet.org/manu67230?n=boehler&oc=3&p=m...
