#52Ancestors Invite to Dinner

Who would I like to invite to dinner? Gee, I have so many but I guess I will go with Moshe Ulanovsky, my husband's maternal grandfather since he is the only one who would have any info on that maternal side. I want to know who his wives were (we think there were 6) and which children went to which wives. I want to know who his parents were and who the parents were of my husband's mother's mother. I want to learn why he had so many wives and what he did for a living. We know very little and there is so much we'd like to know that dinner alone would probably just touch the basics.
