About 1890 Alvin R. Bushnell began working in Monterrey, Mexico as a general agent for all the businesses of Joseph Andrew Robertson, the General Manager of the Monterey and Mexican Gulf Railroad based in Monterrey. Bushnell was married, but his wife's name is not known. He may have stayed in Mexico during the Revolution, or he may have returned to the US, perhaps to San Antonio, Texas sometime between 1914-1920.
I am writing a book about Joseph Robertson and would be interested in any available information about Bushnell. I have specific information about him and some photos I would be willing to share.
