Insane asylums in San Francisco California 1881.

Looking for the records of my G Grandmother, Henrietta Merrill in  San Francisco California in the 1880's. There is a possibility that she might have been committed to an asylum  by her husband after 1881.She mysteriously disappeared after a family "scandal" and we have no record of her living in SF, even though that was the family story, and there is no census record of her after 1880, nor record of her in any directories or death certificate. Thank you for the help.
