Looking for information on my father-in-law who was born in Belgium in 1920 and died in Brussels approx. 1999-2000. He & my mother-in-law were divorced in approx. 1948 in Belgium. He had two sons from the first marriage who came to the U.S. He had two additional sons (in Belgium), but I am not sure whether he was married to their mother. Would like to know who these sons are, where they are, etc. I tried to obtain this information at the time of probating of Georges' estate, but was unsuccessful in getting any information from the attorney(s) in Belgium who handled the matter.
