With a growing number of Catholics living in Larchmont, New York—many of them domestic servants who attended Blessed Sacrament Church in New Rochelle or Most Holy Trinity Church in Mamaroneck[1]—the Archbishop of New York, Michael Corrigan, created the parish of St. Augustine in 1892.

The decision to establish a parish was motivated in part by the fact that the Larchmont Manor Company had offered to donate a parcel of land for the construction of a Catholic church within the village.

[2] A building was erected on the northeast corner of Beach and Linden Avenues,[2] half of whose funding came from local non-Catholics.

[1] The church's parochial school, which was staffed by the Sisters of St. Dominic of Newburg, New York, was dedicated in 1912 by Cardinal John Murphy Farley.

[2] The present, Gothic Revival church building was completed after 19 months of construction, and was dedicated on May 21, 1928, in a mass celebrated by Cardinal Patrick Joseph Hayes.
