Joseph married Asenath her father was Pontipher the Priest of the City of ON which was built by Enoch. The Priest were from the line of Seth. This is the reason Jacob/Israel made both of Joseph and Asenath’s Sons a tribe because of their pure lineage. Joseph adhered strictly to the teachings of Jacob. Your deductions remind me of the universal church spoken of in Revelation.
Oh, dear.
Seth was the son of Adam and Even, an ancestor of Noah. Thus all living today are descended from him, since we are all descended from Noah. We are all of the line of Seth.
Enoch was the great-grandfather of Noah. Anything he built was obviously destroyed by the Flood.
Asenath means “holy to Anath,” a major Semitic goddess. There is absolutely no reason from the Biblical account to assume Potiphera (means “he whom Ra has given”) and his daughter were anything but the obvious, worshippers of pagan gods, although we can assume Asenath became a worshipper of the true God after her marriage.
