I have the following reference from an unpublished genealogy manuscript compiled by Samuel W. Pennypacker between 1874-1880 that refers to the family you mentioned.
Pennypacker, Samuel W., Genealogy of the Pennypacker family: including those bearing the names of Pennypacker, Pennybacker, Pennebecker..., unpublished manuscript, Pennypacker Mills, Rt. 73 & Haldeman Rd., Schwenksville, PA 19473. "He was a farmer and miller owning and living upon the property on the Pickering Creek in Chester County which had belonged to his father. He married Sarah Anderson who was b. Feb. 10, 1784. She was the daughter of the Hon. Isaac Anderson who commanded the Penna Battalion of Musketry in the Revolution War and great granddaughter of James Anderson the first settler in Charlestown township. Her mother was Mary Lane who was the great great granddaughter of Samuel Richardson, a member of the Provincial Council and Judge of Phila County in 1688 and of John Bevan whose pedigree is traced by Welsh genealogists to Einion ap Collwyn prince of Wales in the twelth century and of Barbara Aubrey the aunt of that Dillian Aubrey who married the daughter of William Penn. The Aubreys are a noted family in Wales being descended from Sir Reginald Aubrey on of the Norman Conquerors of that country, among whose forefathers according to some authorities were the royal family of France. It is certain that they were very proud of their lineage two hundred years ago. Matthias early began to participate in politics being generally one of the Federal Committee of vigilance for Charlestown. He was president of a meeting Feby 11, 1813 at which it was "Resolved that the conduct of certain individuals who endeavour to mislead the uninformed by traducing and vilifying the character of native American citizens by asserting that the Federalists are aristocratic monarchist tories, traitors and refugees and that they wish to deprive the poor man of his vote is malicious illiberal and unjust." He was elected to the Assembly from Chester County in 1826 and 1827. In 1837 he was elected a member of the Convention which framed the Constitution of Penna and while there he opposed the system of electing Judges and also the insertion in that instrument of the word "white" which for so many ears deprived negroes of the right of voting. July 6, 1844 at West Chester he was chairman of the largest convention the Whigs ever held in Chester County. Aug. 6, 1834 he was chairman of a county meting held at West Chester to denounce the actions of Pres. Andrew Jackson whose proceedings were afterward published in pamphlet form and attracted much attention. In 1831 he was President of an organization of the leading men of Chester County which made the first movement toward the construction of the Phila & Reading Railroad. Its proceedings were published. He was one of the incorporators of that railroad under the act of Assembly approved April 4, 1833. He was a member of the Mennonite Church and had its Confession of Faith reprinted at West Chester in 1835. He died April 4, 1852 leaving a large estate. The Village Record said, "The ink is scarcely dry with which was written the notice of the decease of one of Chester Countys distinguished citizens before we are informed of the demise of another--Matthias Pennypacker. Mr. Pennypacker whose death occurred on Sunday last enjoyed the confidence of his fellow citizens in a large degree. He represented this county in the legislature for several years and was also a delegate to the Convention to amend the Constitution. In every situation he was faithful to the trust committed to his hands." [Margin note: Dr. Joseph Anderson of Ardmore, told me that it was quite an event in West Chester, when Matthias Pennypacker and his wife drove into the town from their home. The horses, the harness, the carriage glistened. The merchants came out from their stores and to the curb to shake hands.--July 1923, J.R. P.]."
