Theodore Guarvarius Cockrill's middle name is also listed as Guvara (the source for Guarvarius is T. G. Cockrill's nephew, William Aaron Cockrill).

Theodore Cockrill was a member of the 1853 Hagans-Cockrill Wagon Train.

T. G. is enumerated living with parents in Analy Township in 1860 Census with $2500 in Real Estate and $100 in Personal Estate. It also appears in his mother's probate records, that he had borrowed significant amounts of money from her while she was alive.

From William Aaron Cockrill (extracted by Rebecca Aileen Cockrill):

He [Theodore] married and there is a son and a daughter. The son Harry became an actor and followed it all of his life. His wife was an actress and there were no children. They finally got to Hollywood and were on the stage and screen for many years until death took them. Last known living in New York City and going by the stage name of Harry Bradley. Theodore lost his first wife and remarried again and there was one daughter by that marriage and she is still alive in San Francisco. Her name is Ellie M. Cockrill never having married as far as we know.

In the biography of his father in the History of Sonoma County, by J. P. Munro-Fraser (San Francisco, 1880) he is listed as "...now a resident of San Francisco."

He is also listed in the same publication as being a charter member and secretary of the Bloomfield Vitruvious Lodge No. 145, F. and A. M. which was "instituted under dispensation May 31, 1860":

The present membership is fifty, and the lodge is in a very flourishing condition. They have a nicely furnished lodge-room, and the stranger entering their cosily furnished hall cannot but exclaim, "Behold how good and how pleasant it is for brethren to dwell together."

A biography of T. G. Cockrill found in the 1881 edition of Contemporary Biography of California's Representative Men, with Contributions from Distinguished Scholars and Scientists is available.

As a Democrat, Theodore G. Cockrill was reluctantly elected Chief of Police for San Francisco in 1874 and served for one year. Thrust in the middle of a violent anti-Chinese movement raging in California at the time, Chief Cockrill continued to enforce racist laws intended to harass the Chinese population, however he was somewhat more open minded in his dealings with the "Chinese problem" than many of his contemporaries. Some of his involvement in the treatment of the San Francisco Chinese population can be found outlined in Richard H. Dillon's The Hatchet Men.

The nortorious, early California outlaw Tiburcio Vasquez, was a guest at the San Francisco city prison for a few days in 1874 under Chief Cockrill's watch. A short description of this incident can be found in California Desperadoes, by William B. Secrest (Quill Driver Books/ World Dancer Press, Inc., Clovis, CA: Sept 2000, 4th printing), p. 144.

There is also a short mention of Chief Cockrill in another of William B. Secrest's very interesting books: Dark and Tangled Threads of Crime: San Francisco's Famous Police Detective, Isaiah W. Lees (Quill Driver Books/World Dancer Press, Inc., Clovis, CA: 2004), pp. 168 & 178. Also included on page 168, is a photograph of Theodore Cockrill probably taken around the time that he was chief of police (and not in any of the family collections which I have seen).

Local newspaper coverage in The San Francisco Alta of Chief Cockrill's retirement, can be found transcribed here. A complete search of the newspapers of the times in regards to Chief Cockrill's public life still needs to be done. However, one also assumes that several records of the times detailing his activities were destroyed during the earthquake and resulting conflagration of 1906.

An obituary for Theodore G. Cockrill, from the San Francisco Daily Morning Call, June 26, 1899, p. 10, c. 3:

The piller in the Bloomfield Cemetery inscribed with T. G. Cockrill's wife, Mary Francis and their daughter, Frankie T. was also believed to contain an inscription for T. G. The stone had fallen over several years ago and it has been assumed (on the Safford list for example) that T. G.'s inscription was on the side closest to the ground. However, with the 2004 restoration of the cemetery and the return of this particular piller to an upright position, it was found that this east face of the obelisk was blank. Though his newspaper obituary states that T. G. is buried in the Bloomfield Cemetery, it is curious that there appears to be no inscription for him. Other photos of this piller can be found on Mary Francis' and Frankie T.'s pages.
