William Willmore was the son of two of Mrs Pleasant’s employees at her Boarding House at 920 Washington Street, he was interviewed by Helen Holderidge for her book on Mrs. Pleasant. One of the stories he told was of the murder of one of MEP’s laundry service employees by a sailor. Later reviews of this incident tended to discount it. However, I theorize Mr. Willmore may have been confusing the details of a horrific incident that did occur to a person within Mary’s network.
One of, if not the earliest mentions of Mrs Pleasant in the mainstream newspapers of San Francisco, is this grainy notice on December 3, 1860 from the Daily Alta newspaper.

Funeral Home Record for December 2, 1860. Cash Paid in Full $155.00

The tragic story of this 17 year old girls death was covered in local papers but without mention of Mrs. Pleasant’s name. In December 1860, Caroline F Park was employed in the home of Fred A. Woodward on Hawthorne Street in San Francisco. Mrs. Pleasant was their housekeeper and resided with them. Reports indicate Caroline was quite attractive and dating a man named Joe Clarkson, a cook on the SS Chrysopolis. She was also possibly seeing a second man named Oliver Cromwell. One Saturday evening, Clarkson, Cromwell, Miss Park and Mrs Pleasant were dining in the kitchen of the home. At some point Clarkson withdrew a razor blade and attacked Miss Park. She ran from the dwelling bleeding. Her assailant was secured by the Woodworths and taken to the police. Caroline died from her wounds and her assailant was executed in June 1861.

This horrific incident mirrors the story Willmore told except it did not occur in one of Mrs Pleasant’s laundries but in a home where she worked and lived. Also, in the area now known today as SOMA (South of Market), was at least one of the laundries MEP did operate. The incident occurred before 920 Washington street opened and seventeen years before Willmore was born, hence the potential for him to have misremembered the exact location of the incident.
Another important note, Miss Park is referred to as Mrs Pleasant’s niece. The victim of this violence was not simply a worker but her family. This again raises the question of the Park family’s relationship to Mary? Caroline F Park was born in Philadelphia. She is the daughter of John Park, the son of Jane Park of Philadelphia, later Xenia, Ohio. As covered in this post–the Park family figures in Mary’s story and two women from the family are recorded as Mrs Pleasant’s “niece” – Caroline F Park and Rebecca Jane Boone, daughter of Anna Park Howard. Additionally, a third member of this family, Caroline M Park Dunn, aka Mrs. Dunn of Cleveland, is mentioned as MEP’s “former” sister in law.
The Parks of Philadelphia (and later Ohio) again fit the profile of James W Smith’s relatives. The main inconsistency in the known narrative is the Park’s origins being North Carolina not Virginia. And thus an intriguing and loaded question arises, is their matriarch, Jane Park of Philadelphia and later Xenia, Ohio, James W Smith’s mother? Link to draft Park Family Tree.
