The source behind the name

USGS GNIS Populated Place names in all 50 states and DC. Features in the historical extract or explicitly named historical are excluded; duplicate decision records with identical identities and coordinates are collapsed. GNIS points identify names, not legal or neighborhood boundaries, current occupancy, school attendance or a statistical population. Nearby Census places and tracts remain separately named geographies. Name completeness and currency vary; this is not a claim to include every locally used neighborhood name.

USGS description & history

In August, 1854, D. J. Oliver and D. C. McGlynn, brothers-in-low, from Menlough, county Galway, Ireland, erected an arched gate at the joint entrance to their ranches with the inscription "Menlo Park" and the date. When the San Francisco and San Jose Railroad reached the place in 1863, it adopted the name for the station. The gate stood until July 7, 1922, when an automobile struck and destroyed the landmark, (Gudde's California Place Names,Stanger, p.152). (US-T121)
