Beginning in 2010, a show titled Who Do You Think You Are? featured a different celebrity each week as they tracked down information about their ancestors. The children of Bethlehem in the 1st century BC didn’t need to do a genealogy search to know who they were however. Every child in Bethlehem from the 10th century BC onward knew they lived in the “city of David,” with many knowing they were a “son of David,” a descendant of that royal ancestor.
