Posted on: Costilla Co. Co Biographies Reply Here: http://genconnect.rootsweb.com/genbbs.cgi/USA/Co/CostillaBios/3 Surname: sanchez, lopez, vialpando, mascarenas ------------------------- i just recently completed a book entitled Some Descendants of Juan Montes Vigil. It lists the descendants of Juan through his two children, Manuel Montes Vigil who married Gertrudis Armijo, and Manuela who married Pedro Ygnacio Sanchez. Pedro Ygnacio and Manuela's descendants where in Ojo CAliente before coming to Chama, CO. Your Francisca Vialpando descends from, Jose Rafael Antonio Vialpando and Maria Josefa Sanchez?, Josefa Sanchez' father was Jose Guadalupe, his father was Jose vicente, his father was Pedro, Pedro's father was Pedro Ygnacio Sanchez and his mother was Manuela de La Luz Montes Vigil. As for Luis Fernando Mascarenas, he was born 1893 in Chama the son of Roque Mascarenas and Manuela Sanchez. He died in Chama in 1942. He is also a descendant of Juan Montes Vigil. There is a new book called The Spanish RE-colonization of New Mexico which details the origins of the Mascarenas family on their arrival and many of the known descendants, however I have not checked to see if the Chama people are in it. Hope this helps, my e-mail address is mariam@vanion.com if you are interested in my book. I have exactly seven left out of 100 that I printed in July.
