The man that helped Julianna introduced himself as Tade Benson, his wife Shade. Their boys were Matthew, Mark, and Luke. Tade had named them after the first three chapters of the Bible's new testament. If he had another son, he would have named him John, but unfortunately, Shade was advised not to give birth again after Luke's difficult birth.
Luke was also named Joshua, shorten for Josh, by his mother. He recently insisted on changing his name due to kids at school who were always playing pranks and making fun of his name by calling out... 'look! Here comes Luke' or 'look over here Luke'.
When he grew tired of all their antics, he begged his mother for a change of name. His mother and brothers hardly call him Luke anymore, except for his father who still does sometimes. Even though most of the family now calls him Josh, his birth certificate and all other important documents had Luke on them as his name.
