yehudayona – in terms of descent after two generations the chain is considered broken, since there wouldn’t be reliable information more than two generations back. The issue isn’t as uncommon as you might think. Intermarriage in this kcountry is no longer a new phenomenon. I know of one person who had been close to his Jewish grandmother but was brought up Catholic and only found out at age forty that he was Jewish and decided to return. Unfortunately there were already a non-Jewish wife and child involved, so it became very complicated for everyone.
