Well as for Bynes her father's surname doesn't really match either, does it? I find surnames in 2006 can be grossly misleading and don't necessarily mean much. In 1900, sure, but at this point everyone's changed their names and intermarried enough that you can't tell who is what by last name. Why wouldn't Eli's father be Jewish? He's Joseph Cross, also the father of actress Flora Cross, who is Jewish but whose mother is apparently not Eli's mother. There are seemingly a bunch of Jewish "Cross"'s out there, anyway. Well in the case of footnotes the point is really - the list is called a list of Jewish people - so the most important part is really whether the person themselves is "Jewish". The mistake I guess many made before is thinking that the most important part was whether one of their parents or something are Jewish. I think adding a quote about Elvis' ancestry however is important since in his case it is a big stretch and it's for the most part, something that biographers added on after his death, so it would definitely be helpful. But in cases like Bynes, Lauren Storm, plenty of others it's really mostly irrelevant if they are not "ethnically" fully Jewish (and besides, that can be found out in their entry), same for the other X-American lists, establishing that someone is Italian-American is good enough, for example, on List of Italian American actors, I'm sure Tina Majorino's mother isn't Italian (with Italians, unlike Jews, you can obviously tell that if someone's mother's maiden name is "Black" they are most likely not Italian) but the source just calls her Italian, so that's good enough for us. Family tree stuff isn't the most important. Plus - of course - most of the quotes in the numbers for people who are half already say they are half - but I'll go over them below here. As for practicing Judaism - well of the people who are half and whose one non-Jewish parent didn't convert in the 1980s - LaBeouf was raised Jewish/practices and the source quoted says he is Cajun also, Scarlett wore a Star of David to a bunch of events, Jake Gyllenhaal was raised Jewish, and the quote says he is only Jewish on his mother's side anyway, Grey raised Jewish, Flynn's mother apparently converted, Feldman raised Jewish and the quote says his mother wasn't, Carter quote says his father is Jewish only, Bynes says she is "Jewish" and we don't even know which parent (actually for the longest time Wikipedia, under someone's assumption, had "Jewish mother". But this was removed once I came in and started purging these assumption games other editors played and started putting in only verified facts )), Bilson quote says she is half Italian half Jewish, ditto for Baldoni, Paxton quote says all we know, that she is Jewish (maybe her non-Jewish parent converted), Peck grew up with a Jewish single mother, he doesn't know who his biological father was and he was likely Jewish anyway, Prepon we don't know which parent, Reed's brother had a Bar Mitzvah and sources/herself have called her "Jewish", Schwartzman - dunno, Sigler mother converted, Thomas raised Jewish, and the source says his father isn't anyway, Vuolo father converted, Wilson raised Jewish, I think that's about it. So, as you can see, for a large number of these, the quote already says that they aren't "ethnically" all Jewish if that was relevant. OK, as for JInfo, yes, it seems to definitely fall under "some guy's website". It does sometime cite sources, right? But often it doesn't. So I would say, yes, generally do not use it.
