Sr. Alvarez Colmenares, My father's family is from Oaxaca. They fled near the end of the revolution, about 1917-1919. My grandparents were Esperanza Ruiz-Pimentel and Felix Colmenares. There were other family members, of German descent, but I am uncertain of their connection. Have you had any success in your research? Thanks for your work; please let me know what you have discovered. I was in Oaxaca de Juarez Sept 2004 for a brief visit (work related). email@example.com I left enchanted and deeply desiring to return.
