Thank you for your followup. I really don't know if Concepcion Espronceda Tamez is the person in my records. The information I have comes from the familysearch.org website, which has some inaccuracies in its records. According to the mormon website, Maria Concepcion Espronceda, my wife's greatgreatgrandmother, was born around in 1840 in Allende, Nuevo Leon, and married Jesus Maria Alanis Espronceda, her Greatgrandfather around 1861. We have yet to further research the Espronceda, Tamez, Cavazos,Montalvo,and Vallejo of my wife's family, which all originates from the Santiago,Montemorelos,and Allende regions of Nuevo Leon. I will keep your information. My e-mail is firstname.lastname@example.org. If interested, we can exchange family trees for further comparisons. Thank YOu. Felipe Ayala.
