"San Francisco Twins," the Brown sisters, are experiencing their first separation in decades, after Vivian, who suffers from symptoms of Alzheimer's disease, was recently hospitalized after a fall inside the Nob Hill apartment she shares with her 85-year-old sister. As Jay Barmann noted yesterday, "Marian can only afford to visit her sister twice a week now because the cab ride is a $30 round trip. Former mayor Willie Brown has vowed to help the twins out, and he's encouraging people to make donations to the San Francisco Emergency Fund at Jewish Family and Children's Services."

In addition to the JCSF, someone also set up a Go Fund Me account for the twins. The goal is to raise $50,000 for the iconic duo. So far they're at $200. You can donate here.

We here at SFist, of course, wish both sisters the best during what must be a terrible time. Very sad.
