He worked as president of the Bank of Pennsylvania and was one of the founders of the Insurance Company of North America. He served as a Federalist member of the Pennsylvania State Senate for the 1st district from 1811 to 1813.
Barclay was born in Ballyshannon, Ireland[1] on January 22, 1749.[2] He emigrated to colonial-era British America in 1778, as the American Revolutionary War entered its third year, and resided in the revolutionary capital of Philadelphia.
Once arriving in Philadelphia, Barclay obtained work as a shipping merchant, and served in the Continental Army during the American Revolutionary War. He enlisted in 1775 and was commissioned an ensign in 1776; he was eventually promoted to lieutenant and captain. He retired from the Continental Army in 1781.[2]
He was appointed a justice of the peace in 1782 and rose to President Judge of the Courts of Bucks County in 1789.[2]
He was one of the 15 aldermen selected to serve in Philadelphia under the city charter of April 1790. He was a member of the Constitutional convention of 1790, and served as mayor of Philadelphia from 1791 to 1792.[3]
He became president of the Bank of Pennsylvania after the Pennsylvania General Assembly established its charter in 1793.[4]
He was one of the founders of the Insurance Company of North America in 1792, and served as a director of the company until 1793.[2]
He was elected to the Pennsylvania State Senate for the 1st district, and served from 1811 to 1813.[5]
He was married twice. He married his second wife, Mary Searle, at Christ Church in the present-day Old City section of Philadelphia on December 11, 1781, and they had five children.[5]
He died in Philadelphia in 1824 and is interred in the Neshaminy Church Cemetery in Warwick Township, Pennsylvania.[6]
