From 1880 until 1923, the office of postmaster for Dublin (Bucks County, Pennsylvania) was held at various times by J. S. Rickert, Benjamin F. Shearer, and Jacob B. Rosenberger, depending on the political affiliation of the mayor. In 1923, Jacob M. Kooker became postmaster and re-located the post office to his general store. Kooker retired in 1944; the post office remained at the site until 1975. The Dublin Post Office records, 1880-1945, consist of Postmaster's Account and Record Books (4th Class), registers of money orders issued and received, and records of registered letters received and delivered.
