Looking for the name Bourgaux in Charleroi 1860s-1880's.

My records show Michel Bourgaux(born about 1840) and Josephine DeGreve as parents. They had at least two children who were born in Charleroi:

Emile Joseph Bourgaux (born 26 Nov 1866 in Gilly according to obit) and Julia Stephanie Bourgaux (born 29 April 1876).

The family immigrated to the U.S. and eventually settled in Louisiana.

Any help is appreciated.
