Ashkenazi Jews descend from 350 people, study finds
‘Bottleneck’ dates back 600 to 800 years, genome analysis shows; researcher says among population ‘everyone is a 30th cousin’
The study, published in the Nature Communications journal Tuesday, was authored by Shai Carmi, a computer science professor at Columbia University, and more than 20 medical researchers from Yale, Columbia, Yeshiva University’s Albert Einstein College of Medicine, Memorial Sloan-Kettering Cancer Center, Hebrew University of Jerusalem and other institutions.
Researchers analyzed the genomes of 128 Ashkenazi Jews and compared them to those of non-Jewish Europeans in order to determine which genetic markers are unique to Ashkenazi Jews. They found that the Ashkenazi Jews’ genetic similarities were so acute that one of the study’s researchers, Columbia professor Itsik Pe’er, told the Live Science website that among Ashkenazi Jews, “everyone is a 30th cousin.”

About the 56 men who signed the Declaration of Independence:
Five signers were captured by the British as traitors, and tortured before they died.
Twelve had their homes ransacked and burned.
Two lost their sons serving in the Revolutionary Army; another had two sons captured.
Nine of the 56 fought and died from wounds or hardships of the Revolutionary War.
What kind of men were they?
Twenty-four were lawyers and jurists.
Eleven were merchants,
nine were farmers and large plantation owners;
men of means, well educated, but they signed the Declaration of Independence knowing full well that the penalty would be death if they were captured.
Carter Braxton of Virginia, a wealthy planter and trader, saw his ships swept from the seas by the British Navy. He sold his home and properties to pay his debts, and died in rags.
Thomas McKeam was so hounded by the British that he was forced to move his family almost constantly. He served in the Congress without pay, and his family was kept in hiding. His possessions were taken from him, and poverty was his reward.
Vandals or soldiers looted the properties of Dillery, Hall, Clymer, Walton , Gwinnett, Heyward, Ruttledge, and Middleton.
