What is it that every person has, even if he or she doesn't like it? Give up? It's a name!
Sometimes we like our names, and sometimes we'd rather have a different one. Parents often have many reasons for choosing the names they give to their children.
Many times, people choose a certain given name because it is common in the family. It's a way of giving an inheritance of history. This is especially true with the names of grandparents or great-grandparents.
The names within a family often indicate the family's cultural origins. If your name is Dylan or Ceredwen, it could indicate a Welsh heritage. A name like Sven or Bjorn would point toward a Scandinavian heritage. Names like Bridget or Kenneth are common to Scottish and Irish families.
