The origins of Issac Greenspan, my Grandfather are unknown. He was running from the "long arm of the Czar" and never spoke about siblings or where he was from. He was born in 1860 and died in 1904. The idea here is that the most closely matching males share a close geographic origin to Issac Greenspan. Please refer to the Map of where we know men who are close to Issac's lineage, genetically, came from.
