Unlike my 2nd great-grandfather Philip Bourguignon, I do know my 2nd great-grandfather Samuel Zimmerly's date of death. Based on his obituary, Samuel died circa November 20, 1887. A history of the Zimmerly family states that he died on November 20, 1887, while the obituary below mentions that he died the day before the publication date of November 22, 1887.
Zimmerly was a member of Co. B, 1st Infantry, of the California Column. The obituary mentions other members of the same company including Samuel C. Meek, Joseph D. Emmerson, Richard Patterson, Councilman McCuistion, E.L. Smart, and Sam Creevy, all who were residents of the city of Socorro and its vicinity.
