Whatever Happened to Annie Taylor Wenzel?

Annie Sarah (Or Sarah Annie) Taylor married Peter Wenzel in Dutchess County, New York about 1879. This is the Annie who was born in Safe Harbor, PA about 1862 to Hellen Walker Taylor and the unknown Mr. Taylor (George or Harrison?). Annie and Peter Wenzel had about 8 children, at least three survived; my grandmother Flora (Florence Sarah) being one of the first was born in 1882 in Poughkeepsie, New York, and the others were Carrie, who married Patrick Morris, and George. Florence left home at about age 19 with William Carl Lieberknecht and was living in Jersey City, New Jersey where my mother, Ottilie, was born in 1908. Florence and William along with Ottilie were in Detroit, MI in 1910 and in 1911 arrived in Los Angeles setting down (so to speak, but not for long) in Santa Barbara where Barbara was born in the "Anapamu House." I have a photo of Ottilie and her sister, Barbara in Oxnard with a woman who looks like Florence and may be her mother, Annie. They are on the breakwater about 1916, and Ottilie looks to be around 8 years old. The woman could be Annie as she looks very much like Florence had looked at the same age.

So, did Annie travel to California in 1916 with or to visit her daughter, Florence? I am unable to find a death record in NY or a burial place for Annie. What happened to her? She does not appear in the 1910 NY Census. Peter is shown as a widower. They had a legal separation in the 1890s. Annie is my missing ancestor.
