Here are a few thoughts about the California State flag from Shel Weisbach - The Museum of the San Fernando Valley.
And a few tidbits . . .
The bear flag’s design is credited to William Todd, nephew of Mary Todd Lincoln.
California’s Betsy Ross was Nancy Kelsy (or Kelsey). Kelsy deserves recognition for a second feat, as a 17-year-old member of the 1841 Bidwell-Bartleson wagon train, she and baby daughter Martha Ann were
the first females to journey to California in a covered wagon. A monument to Kelsy stands in New Cuyama, Santa Barbara County.
The single star on the California flag carried the same symbolism as Texas’ lone star – seeking union with the United States.
In 1836, Governor Juan Bautista Alvarado led a revolt against Mexican rule under a white flag with a single 5-point red star.
The likeness of the bear on the early flag, not being of the best imagery - was often likened, sorry to say, to a pig.
The current design (and refinement) traces to 1911.
