There is a Myth of Jesus being married, but just a myth. If fact I have come across more than one person that claim to trace their lineage back to Jesus,through king David, but I all ways revert back to Rabbi Singer explanation on how that is impossible.
"Mary’s genealogy is completely irrelevant to Jesus’ supposed lineage to King David. For good reason, nowhere in the New Testament is Mary’s genealogy recorded. Matrilineal ancestry is irrelevant to tribe identification. Both the first chapter of Matthew and in the third chapter of Luke contain a putative genealogy of Joseph alone. Although these two genealogies completely contradict each other, neither suggests that Mary was a descendant of king of David. Joseph’s genealogy is irrelevant to Jesus because according to two out of four Gospels claim that Joseph was not Jesus’ father. The author of the Book of Mark, the earliest of the four Gospels, knows nothing of a virgin birth, and accordingly, begins his book with the baptism of Jesus. The Book of John contains no infancy narrative.
Nowhere in the third Gospel, or in the entire New Testament, for that matter, is there a claim that Mary was a descendant of the House of David. On the contrary, Luke plainly asserts that it is Joseph who was from the House of David, not Mary.
To a virgin espoused to a man whose name was Joseph, of the house of David; and the virgin’s name was Mary.
In fact, Luke claims that Mary was the cousin of Elizabeth, who he says was a descendant of Aaron the high priest,1 placing her in the tribe of Levi, not David’s tribe of Judah. Moreover, in Luke 2:4, the author writes that the reason it was necessary for Joseph and Mary to return to Bethlehem was because it was Joseph, not Mary, who was from the House of David.
And Joseph also went up from Galilee, out of the city of Nazareth, into Judaea, unto the city of David, which is called Bethlehem; (because he was of the house and lineage of David.
And lastly, the Bible never mentioned who Mary's parents were,so impossible to trace her lineage.
IMO, if you believe all mankind began with Adam and Eve, then we are related to Jesus.
