Morton was born in Ridley Township, in Chester County, present-day Delaware County, in 1725, the exact month is unknown. His father, John Morton, was Finnish, who originated from Finland, then a part of the Realm of Sweden, with his great-grandfather, Martti Marttinen, or Måns Mårtensson, himself a native of Juva, Finland, who had arrived in the Swedish colony of New Sweden in 1654. His mother, Mary Archer, was also of Finnish descent. Morton was the only son of his father who died in 1724 before Morton was born. When Morton was about seven years old, his mother married John Sketchley, a farmer of English ancestry, who educated Morton. About 1748, Morton married Ann Justis, the great-granddaughter of Finnish colonists to New Sweden. The couple would have eight children. Morton was an active member of the Anglican Church in Chester County.
Political career
Morton was elected to the Pennsylvania Provincial Assembly in 1756. The following year he was also appointed justice of the peace, an office he held until 1764. He served as a delegate to the Stamp Act Congress in 1765. He resigned from the Assembly in 1766 to serve as sheriff of Chester County. He returned to the Assembly in 1769 and was elected Speaker in 1775. Meanwhile, his judicial career reached its pinnacle with his appointment as an associate justice of the Supreme Court of Pennsylvania in 1774. Morton was elected to the First Continental Congress in 1774 and the Second Continental Congress in 1775. He cautiously helped move Pennsylvania towards independence, though he opposed the radical Pennsylvania Constitution of 1776. When in June 1776 Congress began the debate on a resolution of independence, the Pennsylvania delegation was split, with Benjamin Franklin and James Wilson in favor of declaring independence, and John Dickinson and Robert Morris opposed. Morton was uncommitted until July 1, when he sided with Franklin and Wilson. When the final vote was taken on July 2, Dickinson and Morris abstained, allowing the Pennsylvania delegation to support the resolution of independence without dissent. Morton signed the Declaration on August 2 with most of the other delegates. Morton was chairman of the committee that wrote the Articles of Confederation, although he died, probably from tuberculosis, before the Articles were ratified.

Morton's grave remained unmarked until October, 1845, when the present-day 11-foot marble obelisk was erected by his descendants.
