Originally located along Los Gatos Creek, the town was 550 feet above sea level.

[2] Lexington started out as a sawmill built in 1848 by Isaac Branham and Julian Jank.

[3] In 1880, a narrow gauge railroad from Los Gatos to Santa Cruz was completed, bypassing Lexington and accelerating its decline; its post office had already been transferred to Alma, a mile south, where the trains stopped and which was the transfer point to stagecoaches until the line was completed.

[4] The railroad ceased operations in March 1940, following major damage by a winter storm[5] and the completion of State Route 17 that same year.

Three men were responsible for the brutal murders of William Peter Renowden and Archibald McIntyre in Lexington, on March 11, 1883.
