Obituary of Jonathan Silliman included in the June 1885 edition of the Obituary Record of Graduates of Yale College. He was for many years a minister at Cornwall, New York.
The last few pages of this booklet are a Summary of the deceased graduates and an index, all pages of which appear at the end of this post.
Jonathan Silliman was born in Chester, Conn., July 22, 1793, and died in Cornwall, N.Y., May 13, 1885, aged nearly 92 years. He was the son of Deacon Thomas and Huldah (Dunk) Silliman, and the grandson of the Rev. Robert Silliman (Y.C. 1737)
He studied theology in Andover Seminary, teaching meantime for one year in Phillips Academy, and finishing his professional studies in 1821. He soon went South and labored as a home missionary in eastern Virginia, being ordained on October 8, 1823. In 1830 he was settled over the Presbyterian Church in New Kent, Va., and on September 5, 1832, he married Anna, daughter of the late Rev. Dr. Amzi Armstrong, of Perth Amboy, N.J., and widow of Mr. Jared Mead; she was a women of remarkable intelligence. As both his own and his wife's health suffered from the Virginia climate, they returned to the North in 1835, and in the same year he was installed over the Canterbury Presbyterian Church in Cornwall, Orange County, N.Y., where he labored in the ministry until his voluntary retirement in 1862. He continued his residence among his former people, and his benign presence was felt as a benediction.
His wife died January 24, 1882. Their only child, a colonel in the Union army, died at Beaufort, S.C., in 1864.
From online research, hopefully correct: [corrections and additions welcome!]
Their son was William Silliman, born 18 October 1837 at Canterbury (now known as Cornwall), New York. He married Mary Louise FitzRandolph on 18 March 1864 and died of wounds a few months later on 17 December 1864 at Beaufort, North Carolina, while a colonel with the 26th Infantry Regiment U.S. Colored Troops. I don't believe they had any children, and it appears that Mary Louise never remarried.
