This “shore” refers to a pair of brothers from Toronto: Thomas Edwin Egerton Shore (1871-1944), who went by “Egerton”, and Allan Shore (1873-1947). The elder Shore was a high-ranking Methodist missionary while the younger was a physician. In 1913, they both abruptly quit their jobs and left for sunny California, hanging out their realtor shingle in Hollywood the following March. We can guess at the Shores’ motivation behind giving up their stately vocations and moving to Tinseltown but it should be noted that Margaret Shore, the three-year-old daughter of Egerton and his wife Harriet, died that October of tuberculosis meningitis, so it’s possible that they’d brought her here for her health. At any rate, the Shore brothers opened the Shoreham Heights tract, as well as the West Knoll tract down the hill, in 1921.
