Eloise Hammond Trowbridge

The second sister of the Trowbridge family, born abt. 1877 in Nevada.  (The two middle-aged pictures, taken abt. 1913 when she was abt. 36, are tentative, but it seems like it's got to be her.)

She attended Cal, class of 1901 (1), but didn't graduate, and also attended the San Francisco Art Institute (2). This painting is hers.
 

She married Frank Freeman Ellis (b. 1875), a teacher in the Smith-Hughs program at Fremont High School in Oakland (3).  According to family stories they had no biological children, but adopted an earthquake baby.  Their daughter Hope would have been born around 1906 (4), the year of the SF earthquake.  (Pic of Frank Ellis is from his passport application.  Pic of Hope is a tentative ID from a picture of various family members.)

In August 1918 Frank applied for a passport to go to Europe with the YMCA (5), to aid the war effort towards the very end of the war.  His brother-in-law Wallace Turner (husband of Eloise's sister Kate Elliot) also went with the YMCA, around the same time.

By 1920 Eloise and Frank had a niece living with them, Olive Trusty, age 5, daughter of Eloise's youngest sister Olive Rose.  From this it would seem that Olive Rose had died. 

In 1923 Eloise died, at the age of 46, we don't know why.  Olive Trusty ended up with other relatives in LA (6).  One year later Frank married Kate Elliot, also widowed.  My grandmother Elliot and her two younger siblings became Frank's step-children. The daffodil painting is in my family because of this.  Three years later, in 1927, Kate Elliot herself died in childbirth.

 This picture is from a photograph of the two younger step-kids, Wallace Jr. and Ruth, with "Dad," from Spring 1928.  We know that Wallace and Ruth continued to live with Mr. Ellis for some period of time after Kate Elliot died in 1927, so this has got to be him. 

Frank Ellis then married Gladys Charles, nee Maul, who had a son from her previous marriage (coincidentally also named Elliot).  Frank and Gladys had one child, Barbara Minora Ellis (Frank's only biological child, though he parented six others). (7)
