Twins get 'mystifying' DNA ancestry test results

According to 23andMe's findings, Charlsie has nearly 10 per cent less "broadly European" ancestry than Carly. She also has French and German ancestry (2.6 per cent) that her sister doesn't share.

The identical twins also apparently have different degrees of Eastern European heritage — 28 per cent for Charlsie compared to 24.7 per cent for Carly. And while Carly's Eastern European ancestry was linked to Poland, the country was listed as "not detected" in Charlsie's results.

"The fact that they present different results for you and your sister, I find very mystifying," said Dr. Mark Gerstein, a computational biologist at Yale University.

Twins' DNA 'shockingly similar'

Marketplace sent the results from all five companies to Gerstein's team for analysis.

He says any results the Agro twins received from the same DNA testing company should have been identical.

And there's a simple reason for that: The raw data collected from both sisters' DNA is nearly exactly the same.

"It's shockingly similar," he said.

The team at Yale was able to download and analyze the raw data set that each company used to perform its calculations.

An entire DNA sample is made up of about three billion parts, but companies that provide ancestry tests look at about 700,000 of those to spot genetic differences.

According to the raw data from 23andMe, 99.6 per cent of those parts were the same, which is why Gerstein and his team were so confused by the results. They concluded the raw data used by the other four companies was also statistically identical.

Still, none of the five companies provided the same ancestry breakdown for the twins.

"We think the numbers should be spot on the same," Gerstein said.

State approves use of familial searching to help identify crime victims

 State approves use of familial searching to help identify crime victims

Until now, the use of familial searching was just limited to identifying suspects. Investigators will have to wait for about two months for the technique to get all the necessary approvals to start using it. To read the article in Newsweek hit here

From Mexico City to Santa Fe

Presented by Henrietta Martinez Christmas

The Camino Real from Mexico City to the Villa of Santa Fe in the northern province of New Mexico where the land was unknown and isolated. The Camino Real permitted the founding of many mining centers and agricultural areas which today constitute some of the oldest cities in the northern central area of the Republic of Mexico and the Southern United States.

Henrietta Martinez Christmas, a prolific speaker, has given hundreds of presentations on topics related to Hispanic/Southwestern research. Engagements include: keynote – Santa Fe Trail Association, featured at annual conferences: Texas Genealogical Society, Historical Society of New Mexico, DAR and BIA, International Conference.

A native New Mexican, Ms. Martinez Christmas is a well-known genealogical and historical researcher. She descends from 11 of the soldiers that came with Juan de Oñate in 1598. She has written several books which relate to New Mexico’s small town and history and over 150 articles about New Mexico’s Colonial Families. She is a long-time member and the current President of New Mexico Genealogical Society. She has worked with the History Museum of New Mexico, the Albuquerque Museum, and the El Camino Real Heritage site in preparing exhibits and researching historical data. She is a frequent contributor to various author’s books in terms of researching biographies of noted individuals in books. She works with a group that honors historic women in New Mexico for their New Mexico Historic Marker Program. Honored by the DAR for historic preservations, she has extracted and transcribed over 50 books dealing with early New Mexico.

Panes Updates

 

Sylvia Magdaleno continues the inexhaustible work of transcribing documents from repositories that give information about various towns in Chihuahua. Her latest completed transcriptions are of the 1778 census of some small towns surrounding Cusihuirachi. They include Cajurichic, Usuachi, Coyeachi, Hacienda de la Consepción, Hacienda de la junta and Cerro Prieto. The organization is forever greatful for all the work that she does, work that may give one of our readers that long, lost link that they have been looking for.     It gives us great pleasure to announce that the Spanish Inquisition project of organizing a catalog for the images that are already on FamilySearch has begun. With the help of the Colegio de Michoacán, the Hispanic Heritage project has contracted with Dr. Isabel Juárez Becerra, who is the coordinator of the project, to make the catalog. She is directing a group of students from the university and they have now transcribed three of the rolls of microfilm. The transcriptions will be used for putting data in their catalogs. You can purview these films online at panes.info. However, unfortunately, our budget cannot sustain the cost of this project without more funding. As you know, Hispanic Heritage Project is a non-profit organization and we depend totally on donations. We invite you to donate so that we can continue this valuable project. You may donate at the same site, Panes.info. Again, if you would like to participate in helping to transcribe, please contact by email to cmyturralde@gmail.com.     ©2020 Hispanic Heritage Project | 3611 Foxley Drive, Escondido, CA

Be Consistent

When entering items in your genealogical database, be as consistent as possible. While some things can vary from one individual to another, such as last names, other things do not. Transcriptions should always render documents and records as they were recorded and originally written.
