My family is from Puerto Rico, we are only two branches of Belens, of course coming from the same familly. I found Belen as a german last name, but my grandfather looked like an arab, dark skin, waivy hair. Several lawyers, such as Edwin Belen are part of the other branch of the family. I have several brothers Edwin, Ernesto, and Ivan Belen. My father is Ernesto Belen Serrano. I would like to know why our last name is uncommon, rare.
