Dublin was founded in the early 19th century by George McCausland and a friend who migrated from Dublin, Ireland. This site is where George McCausland operated a tavern. His house was across the street on Rte 440. In 1858 the town had ten houses and places of business. Dublin had a post office in 1878, one of the first in Harford County. Dublin school was a part of the public school system in 1867 with a one-room building on present-day Route 136 across from the present school. By 1878, Dublin boasted two stores, a blacksmith shop, a wheelwright shop, a hoop maker, a tailor shop, one school and two churches, Dublin Methodist Episcopal Church and for the southerners Southern Methodist Episcopal Church.
Currently Dublin has a population of 13,075 people and encompasses 80.2 square miles. It is an unincorporated community in Harford County, Maryland. This can be a busy spot on a hot summer day, so be discreet. This is private property, but I have permission to place cache here.
