Enumerated with her parents in the 1850 Census for Bates Co., MO. Enumerated with James A. Cockrill in the 1852 California Census for Sonoma Co.

After Mary married James M. Case, the pair disposed of the 160 acres of property which James Cockrill had supposedly purchased (though probably squatted upon first) from Julio Carrillo in 1852, though ownership was not clear until the Californio and Spanish ownership issues in California were cleared up by the courts in the 1860's. Starting in 1854, the Case's sold the land in three portions, with Henry Beaver eventually ending up as owner of the original 160 acres.

In 1857, during the William A. Buster embezzlement scandal, the Cases, along with Buster, James E. Crane and Joseph Browning had to sell by a sheriff auction, two city lots which they had invested in. These lots (186 and 187) were in Block 15 between Second and Third Street, facing Main Street in Santa Rosa. They were one block up from the 6 lots which Harrison Cockrill purchased on August 7, 1855 (and latter became known to the Cockrill and Fulkerson families as the "Chinatown Property").

Mary and James then appear to have moved to Colusa County and then to Yolo County for a period of time. I have been unable to find them in the 1860 Census. However, James Case is listed as a resident in Colusa County in a lawsuit filed by Jeremiah Claypool on January 23, 1865, and both Cases are named as plaintiffs with Yolo County residences in 1866, in the two lawsuits (561 and 657) which Mary's step-daughter, Ellender (or rather her husband) filed to seek renumeration for the selling of her father's land to Henry Beaver. Though these two suits indicate more rancor directed towards Henry Beaver, one could probably assume that Mary Case did not get along with her step daughter. That the 1857 marriage between the 14 year old Ellender and the 32 year old Jeremiah Claypool was allowed to occur, probably had something to do with Mary wanting her stepdaughter out of the house as well as allowing the Cases to move away from Sonoma County with one less mouth to feed.

Mary is enumerated with James M. Case and living in Alviso area of San Jose in the 1870 Census for California (see complete listing under the notes for James M. Case).

Later census records for her remain to be found.

In a note by Jeanne Miller, had 5 children by James Madison Case: Kate, John, Belle, Dualy, and Lizzy. The 1870 Census, confirms the names John W., Sarah M., and Lizzie M. In the obituary for Walter C. Cockrill, it is mentioned that he had two sisters, Mrs. Kate Heacock of Modesto and a Mrs. Elizabeth Bell of Long Beach.

Mary eventually got a divorce (see note under James M. Case) as a result of husband's "extreme cruelty."

What happened to her? Believed by Dr. Baker to have moved to Salinas after her divorce from Case and stayed with Henry Beaver's family. Since this supposedly occurred in 1887, after Henry and his family left the area, this then is very unlikely therefore. However, she may have stayed with one of Henry Harrison's children (Eliza McGuire?) or left Case much earlier.
