Latinos with traditions of Spanish Jewish ancestry
David Kelly. "DNA Clears the Fog Over Latino Links to Judaism in New Mexico." Los Angeles Times (December 5, 2004). Excerpts:
"He [Father William Sanchez launched a DNA project to test his relatives, along with some of the parishioners at Albuquerque's St. Edwin's Church, where he works. As word got out, others in the community began contacting him. So Sanchez expanded the effort to include Latinos throughout the state. Of the 78 people tested, 30 are positive for the marker of the Cohanim, whose genetic line remains strong because they rarely married non-Jews throughout a history spanning up to 4,000 years. Michael Hammer, a research professor at the University of Arizona and an expert on Jewish genetics, said that fewer than 1% of non-Jews possessed this marker. That fact - along with the traditions in many of these families - makes it likely that they are Jewish, he said. ... It also explained practices that had baffled many folks here for years: the special knives used to butcher sheep in line with Jewish kosher tradition, the refusal to work on Saturdays to honor the Sabbath, the menorahs that had been hidden away. In some families, isolated rituals are all that remain of a once-vibrant religious tradition diluted by time and fears of persecution. ... 'We believe a fairly high percentage of first families [arriving] in New Mexico were nominally Catholic, but their secret religion was Judaism,' he [Bennett Greenspan of Family Tree DNA] said. "We are finding between 10% and 15% of men living in New Mexico or south Texas or northern Mexico have a Y chromosome that tracks back to the Middle East.' They are not all Cohanim, and there's a slight chance some could be of African Muslim descent. But Greenspan said the DNA of the men is typical of Jews from the eastern Mediterranean."

"Growing up in the Rio Grande Valley, Danny Villarreal had heard the stories from his grandparents. His ancestors, it was whispered, had come to Mexico from Spain under something of a cloud. Apparently, they were not purebred Castilian Spaniards, but members of a persecuted minority -- namely, Jews who had converted to Catholicism on pain of death at the hands of the Spanish Inquisition. ... FTDNA sent the test off to a genetics lab at the University of Arizona, and a few weeks later Villarreal got his results back. Although the company didn't find that he was related to anyone then in its database, it did have a few surprises for him. First, there was his haplogroup -- the genetic marker that goes back on his Y chromosome for tens of thousands of years. All humanity is divided into 18 of these, and Mexicans of European descent would likely be in either haplogroup R-1A or R-1B, the most common groups in Western Europe, or if they were primarily of Native American descent, Q or Q-3. Villarreal's was E-3B, which is a Semitic haplogroup that evolved in East Africa and then spread around the Mediterranean and is most common today in the Middle East and in North and East Africa. Then there were his closest genetic matches. All three of them were to Jews in places like Hungary, Belarus and Poland."
Simon Romero. "Hispanics Uncovering Roots as Inquisition's 'Hidden' Jews." The New York Times (October 29, 2005). Excerpts:
"When she was growing up in a small town in southern Colorado, an area where her ancestors settled centuries ago when it was on the fringes of the northern frontier of New Spain, Bernadette Gonzalez always thought some of the stories about her family were unusual, if not bizarre. Her grandmother, for instance, refused to travel on Saturday and would use a specific porcelain basin to drain blood out of meat before she cooked it. In one tale that particularly puzzled Ms. Gonzalez, 52, her grandfather called for a Jewish doctor to circumcise him... Ms. Gonzalez started researching her family history and concluded that her ancestors were Marranos, or Sephardic Jews, who had fled the Inquisition in Spain and in Mexico more than four centuries ago. Though raised in the Roman Catholic faith, Ms. Gonzalez felt a need to reconnect to her Jewish roots, so she converted to Judaism three years ago. ... These conversions are the latest chapter in the story of the crypto-Jews, or hidden Jews, of the southwestern United States and northern Mexico, who are thought to be descended from the Sephardic Jews who began fleeing Spain more than 500 years ago. The story is being bolstered by recent historical research and advances in DNA testing that are said to reveal a prominent role played by crypto-Jews and their descendants in Spain's colonization of the Southwest. ... Family Tree DNA, a Houston company that offers a Cohanim test to its male clients, gets about one inquiry a day from Hispanics interested in exploring the possibility of Jewish ancestry, said Bennett Greenspan, its founder and chief executive. Mr. Greenspan said about one in 10 of the Hispanic men tested by his company showed Semitic ancestry strongly suggesting a Jewish background. (Another divergent possibility is that the test might suggest North African Muslim ancestry.)"
