Other than these records, and a potential find in the 1899 Tucson City Directory, I had little to go on for Manuel. But working backward through 1841 images in the Defunciones 1900-1916 (death records) for Hermosillo proved to be quite useful.
On 6 October 1903, Manuel and Teresa lost a 10 month old son, Ramon Portillo, in Hermosillo. I knew from the 1940 US Census that Teresa had 10 children, so this was the first record of a child of theirs who did not make the journey to America.
