I am now pretty sure that my German great-grandmother's biological father was not her official / legal father (the explanation for at least some of my Jewish DNA). So I want to add the line for the person I think was her biological father to my ancestry tree (I have enough DNA matches to narrow it down fairly closely, thought I would put XXXX Surname rather than a particular man's name, but then I can add his parents and work back from there, and maybe figure out connections with more of my matches that way.)

Should I do it as "Add Alternate Mother / Father"? Does anyone know whether the new line will then show up in my "pedigree" when DNA matches look at my details (which is how I want it to work.) Or is there another way of doing it? I don't want to delete the official line especially since I'm not 100% sure.
