Born, April 4, 1786, Philadelphia, the son of Michael and Maria Hay, Peter was a Philadelphia printer, alderman, and publisher of the Washington Whig, 1815, an anti-Federalist journal supported by the “democrats” of the Washington Whig Society. Although Peter sold the journal in 1817, in 1821, the paper represented the political ideology of the “old Jefferson Men” in support of national Republican John Quincy Adams (ant-Jackson). Hay served a single four-year term in the state Senate, 1826-1830. From 1830 to 1838, he continued business as Peter Hay & Co. Printers. On January 10, 1854, Hay served as secretary to the “War of 1812 Commemorative Convention” in Philadelphia. He married Eliza Young, daughter of John Young of Millville, 1815. He died in November 1879, Philadelphia.
