John Y. Clark Papers


This directory contains transcriptions of letters to and from John Yardley Clark, from about 1834 to about 1841. Much of this correspondence is between John Y. Clark in Paris and his brother James G. Clark, who was still living in the Philadelphia area. The original letters were transcribed by Mrs. Margaret Lewis Irwin, and are being posted publicly here for anyone interested in this bit of history.

John Yardley Clark was born in New Jersey on March 3, 1797. He graduated with a degree in Medicine from the University of Pennsylvania. On December 19, 1820, he was married to Ann Eveline Fries, daughter of John Fries. She was born Aug. 20, 1796 and died July 18, 1826. They had two children, Evalina, born Sept. 12, 1822 - she died at birth, and John F. Clark, born June 12, 1825 - died June 10, 1835.

John Y. Clark was married for a second time on June 29, 1829, to Henrietta (sometimes known as Harriet) Girard L'Allemande. She was a niece of Stephen Girard and the widow of General L'Allemande. She had a child, Caroline, by her first husband. Caroline married into French nobility. John and Henrietta had three children - Roma, b.? d. 1832, Henry, dob unknown and Florence (Flory) dob unknown - d. 1930.

After living in Paris for many years - on the rue de Rivoli - John Clark returned to America in failing health around 1853 and died in Philadelphia on May 29, 1863. Harriet Girard-Clark died in 1880 and her obiturary was published in the New York Times on July 29, 1880.


More information can be found by searching for "John Y. Clark" at The Historical Society of Pennsylvania, which has the James G. Clark Papers, 1839-1866, which apparently are also referred to as the John Y. Clark Papers, because they are primarily letters from John Y. Clark to James G. Clark. (Presumably the letters at The Historical Society and here on this web site are different.)

Dunlap House Presuming there aren't multiple people named John Yardley Clark in this time period in Paris or the Philadelphia area, there are a number of additional interesting facts one can learn about him on the internet. He received his M.D. from the Medical Department of the University of Pennsylvania in 1818. His notes on medical lectures by Dr. John Syng Dorsey in 1816-1817 are in the archives of The College of Physicians of Philadelphia. He was a member of The Academy of Natural Sciences of Philadelphia, and in 1824 was a founding secretary of The Pennsylvania Society for the Promotion of Internal Improvements in the Commonwealth. "The History of the Pennsylvania Hospital, 1751-1895" (p. 337) records that he donated a Piano Forte for the use of the Insane Patients. According to History of Philadelphia, 1609-1884, by J. Thomas Scharf and Thompson Westcott (p.926), he lived in the John Dunlap House (at left, as shown in the book) from 1825-1828.

To Do: I should add more information about the family tree. One relative (grandfather?) was John Fries, who was involved in the Whiskey Rebellion. One of John Clark's descendants was a math professor at Oxford, and other interesting ones as well.
