Yad L'achim announced last week that in January they had several cases in which Arab women turned to the organization for help and thereby discovered their Jewish identities.
These women had lived their entire lives as Arabs, grew up in Arab villages and were taught Arab beliefs, lived as devout Muslims, and never suspected themselves to be Jewish. were born to a Jewish mother and a Muslim father, and did not know their mother's true identity.
Both sides (usually the singles themselves, parents, close relatives or friends of the persons involved) make inquiries about the prospective partner, e.g.
on his/her character, intelligence, level of learning, financial status, family and health status, appearance and level of religious observance.
Nothing says Ayshet Chayil like her ability to lovingly prepare a Seder plate. Don't think this means Jewish women are controlling.
