In the late 1800s, the land that is now home to the Three Palms Vineyard was a residence for famed San Francisco socialite Lillie Hitchcock Coit. She called her home Larkmead, and it was here that she hosted legendary parties and numerous celebrities of the time. Mrs. Coit is best remembered in San Francisco for her devotion to the Knickerbocker Fire Engine Company #5. At the age of seven, Mrs. Coit was rescued by a firefighter from a burning hotel. To repay her debt, she became the fire engine company's patron and an honorary member. She left her mark on San Francisco in the form of Coit Tower. She left her mark in the Napa Valley in the form of three lone palm trees, which were all that remained from her estate after the house fell into disuse and ruin. Lillie died in 1929 at the age of 86.
