My name is Marie (Stella) Cardoza, and I have been researching the Esquer family for over 20 years. My Esquer family tree descends from Francisco Joseph Esquer and María Nicolasa Murillo. The family is primarily, but not exclusively, from Culiacán, Sinaloa and Alamos, Sonora, Mexico. This family connection dates back to the early 1700s. Juan Salvador Esquer, who was born in Isaba, Navarra, Spain immigrated with his children to Mexico in 1695. His children established the Esquer name in northern Mexico, but I have not had any success finding documentation to prove how Francisco Esquer was related to Juan Salvador Esquer,until now. Turning to science, I have recently proven that relationship through Y-DNA analysis. DNA was gathered and analyzed through a simple painless cheek swab. If you are a male, and carry the name “Esquer/Ezquer,” you might consider participating in the Esquer Family DNA Project. You can do so by going to the Relative Genetics website at www.relativegenetics.com or calling them at 1-800-956-9362. You can also contact me at firstname.lastname@example.org for more details. If your DNA matches, your family connection will be proven, and you will become part of the Juan Salvador Esquer Family Group. This will entitle you to use the Esquer family tree that I am preparing to share with members of the group, at no charge. However, there is a charge for the DNA analysis. I have no financial connection to Relative Genetics, the laboratory that is conducting the DNA analysis. I am simply offering this opportunity as a courtesy to serious Esquer family researchers.
