Family trees shared heritage. The bald face lies they can track their ancestors to the Israelites. Simply see if you can get them to reply to these questions in a public form

No one could possibly trace their family trees 1000 years and DNA matches can only show where a tiny fraction of your ancestors came from. DNA does NOT prove these were your ancestors. You have millions of ancestors and you are a composite of every one of them.

Because high speed connections now exist I have consolidated all pages on family trees into one page here http://encyclopediaegypt.com/israel/f1000.htm
