I just now saw your query on Mary Lash and Antonio G Chavez. Antonio Chavez was my great Uncle and brother-in-law to my grand-mother, Barbara Chavez and brother to my grand-father, Emilio. I have a great deal of family history information on the Chavez family and am willing to share the info. Additionally, I just researched the Staffinger family as it was related to Mary Lash Pike. I have a picture of both Antonio and Mary while in San Diego and am willing to share it.
