It appears that you are looking at another Ancestry member's tree with the names you mention. I looked at that tree but I did not see any sources that directly link Ephraim as the father of Levi. I did some searches for a will or a census but I did not see anything concrete so I would not use them yet. I would use it as a link and continue doing work in this area to find that one item that links the two together and then I would put all that into Wikitree.
