I am researching Antione Dam, Dahme, Dame

born and died in area of Hainault, Berlgium//Cambria, France..... we think he must have been Dutch or German and lived in the area of Hainault that was fought over and under the Spanish, Dutch, Belgian, and French governments in the early years........ I feel the Dame surname is not really true French..... would appreciate if you have any info on an Antoine Dam or his son Antoine Dahm, Dame married to an Elisabeth Francois or le Francois...]
