Re: Rashi's weird genealogy
I'm afraid I don't have a lot of things for you...
There's Nacha Chaya Freyman, my 4th great grandmother in law, born in Krakow in 1817 and married to Michael Zelig Wetzler on 24 October 1842.
And there's Ella Friedman, my 18th cousin in law, the wife of Julius Seligman Oppenheimer and the mother of Julius R. Oppenheimer (1904-1967).
You know, it's common to be stuck with at least one branch of your family tree. Sometimes, if the country/place is not well researched, you'll have to go there yourself and look into the archives, if they haven't been destroyed during WW2.
Personally I would look for Friedmans with slight variations (Fridman, Fredman...), and if I wasn't *totally* sure the whole family was in Hungary I would check this: http://www.jewishgen.org/jri-pl/http://www.jewishgen.org/jri-pl/
I would also do a search on google, with Friedman, Hungary, and maybe the first name of your grandfather or something.
You could also go there http://www.yadvashem.org/wps/portal/IY_HON_Welcomehttp://www.yadvashem.org/wps/portal/IY_HON_Welcome and look for Friedmans in Hungary, and see if there is a place where most of them lived.
Asking the oldest relatives is also a good idea, but I'm sure you knew it. :)
