Talkback, interesting link. A little off subject of the thread, but the Jewish Communities of India might be the longest contiguous Jewish communities, yet the “facts” of that article stating they migrated from Judea before settling in India appear spurious .
No citations or explanation of how the author just knows that they came from Judea — which had a population in the iron age, but was know as Judea under the Romans, much later. Populations came and went.
Hebraic tribes of Hadramaut in Yemen were much earlier and as that is closer to India. As there has always been trade and exchnage with India, the likeyhood that Jews of 2500 years ago in India may have come from what is now Yemen. Hebrew family names are not uncommon in the hills of Yemen.
