The Genealogy of Jesus

Both Luke and Matthew give detailed genealogies of Joseph, going back to Abraham in Matthew, and to Adam in Luke. However, apart from Abraham, Isaac and David, very few names appears on both lists. Presumably, no Christian ever bothers to read these lists, otherwise someone would have spotted it by now.

What is also not explained is why a genealogy of Joseph should appear, as he is not supposed to be Jesus's father - it is completely irrelevant, as Joseph never touched Mary, certainly not with that, anyway!
