This is phenomenal! Thank you so much for posting the books. Any chance of locating Kiev marriage registries from 1896 and 1897? Or at least point me toward them. The marriage index book finally pinpointed my great-grandparents' year of marriage.
One more question: is it possible that more than one Jewish registry existed in Kiev? I know for a fact that both sides of my grandparents' families were born in Kiev, but found only a couple of the children, even knowing exact birthdays.
