The Hallidies, like other wealthy San Franciscans, had a summer retreat on the Peninsula.
Here they pose for this undated photograph with family and friends at Eagle Home Farm on Spring Ridge.
The woman on the left is identified as "Mrs. Baba" (or Baza). Also pictured, from left, is Grandma Eliza Brown, Florence Doyen, Andrew Hallidie, Martha Hallidie, Andrew Smith Brown, Annie Grant Sheppard, and Joe Doyen.
Andrew and Martha Hallidie had moved into the area in 1883, and their 368-acre Eagle Home Farm extended from Portola Road, just across from today's Village Square, up to Skyline, according to "Life on the San Andreas Fault: A History of Portola Valley," by Nancy Lund and Pamela Gullard.
