David,
Somehow, I missed seeing your posting until now. My original posting was in 2008. In 2009, I went to the Family History Library in Salt Lake City, Utah, where I found more information about my great grandparents than I could imagine. I still have many questions, and plan to keep searching through FamilySearch.org. Hopefully, some day, I will also make a research trip to Belgium. Thanks again for your response.
