Between 1850 and 1900, there appeared several groups of immigrants, who settled on Potrero Hill; the Scotch and Irish predominating.

THE SCOTS came to this area in 1865 from the Clyde River area in Scotland to work in the shipyard, and later to work in the Union Iron Works, established in 1883. The area chosen by the Scottish people to be their new homeland was on top of Potrero Hill along Mississippi, Texas, and Connecticut Streets. The name "Scotch Hill" was recognized by its residents at that time.
