History
Founding
Edward Tanner was granted land by William Penn in the Province of Pennsylvania and named it "Upper and Lower Dublin." Lower Dublin was incorporated into the City of Philadelphia following the passage of the Act of Consolidation in 1854. The "upper" portion has continued to exist around the original survey for the laying out and naming of Susquehanna Road. Upper Dublin Township was established in 1701, when William Penn ordered a survey of all townships in the Commonwealth.
