My gg grandfather had 12 siblings. They are: Johann Joseph, Johann Karl (my gg grandfather), joseph, Elizabeth, Philipp, Anna Margareta, Marie, Clara, Margareta, Karl or Charles, another Maria, Unavailable, and Justine. Their parents names were Jean Cuvelier and Maria Guelf. The 1st two Johann's were born in Arlon, Luxembourg, Belgium and the rest in Clervaux, Luxembourg. My info is from Family Search.org and personal research. Would like to exchange info. Email me at jkhouha@yahoo.com. Put Cuvelier in the subject line so I don't delete it. Judy
