History
Hillsborough is located on the Rancho San Mateo Mexican land grant which was purchased by William Davis Merry Howard, son of a wealthy Hillsborough, New Hampshire, shipping magnate, in 1846. Howard settled his family in this area, which attracted wealthy San Franciscans. In 1910, Hillsborough residents voted to incorporate. From the town’s foundation until 1963, it was an exclusive community for wealthy whites. That all changed in 1963 when Jack and Betty Ken, the first-generation children of Chinese Immigrants, purchased land in the town. This made them the first non-white people to own land in the town, which effectively desegregated Hillsborough.
