Yeah, it's pretty wild that even though I'm a Christian, I can make aliyah because my grandmother was Jewish.

Which leads to another question - my husband can make aliyah through my grandmother also, but my kids (who are quite young yet) seemingly cannot? Unless, I assume, I convert to Judaism?

Oh and yet another one - what kind of proof does Israel require of children and grandchildren? How would Israeli authorities determine, and how would one indicate, that a grandparent was Jewish? I imagine that you can't just fly over and say "hey, I claim eligibility" with nothing to back it up.

I'm not sure what would be required as proof. It's my understanding that if you state thay you're a now a Christian, you likely wouldn't be admitted. Obviously you could lie, which could get you deported later. If you were admitted, I believe your minor children would be as well.

The Beth Din, Jewish Legal Court, requires original copies of Birth Certificates of relatives of those people who are interested in making aliyah or confirming their Jewishness. The orthodox Rabbinate are very strict in certain matters. An Australian Jewish girl I know who is marrying an Israeli had to present two male witnesses to the Beth Din who had to testify that she had not been married. (Because he is a Kohanim he cannot marry a divorced woman according to halakha.) One of the Beth Din members remarked that it was unfortunate that the two male witnesses brought before the court were not Jewish.

Halakhic interpretation is a very interesting field. Messianic jurisprudence will eventually reign throughout the world.
