The earliest Christian records, the Pauline epistles make no reference to Jesus' father, and nor does the Gospel of Mark, the first of the Gospels. The first appearance of Joseph is therefore in the gospels of Matthew and Luke, one of which trace Joseph's lineage back to King David. The two lists give differing genealogies: Matthew says that Joseph's father was called Jacob [Mt. 1:16]. Some scholars reconcile the genealogies by viewing the lineage presented in Luke to be from Mary's side.
