Daniel Kelsey moved from Hartford to Huntington about 1710. By deed dated April 4, 1711, he sold his lands at Hartford to his brother, William Kelsey, as follows: "Daniel Kelsey of Huntington on Long Island, New York, for consideration of £13, sells to William Kelsey of Hartford 'my whole right to all my lands in Hartford, Excepting my part of the house and homestead.'"
The Town Records of Huntington show that on May 6, 1712, Daniel Kelsey and James White were chosen to gather the minister's tax for that year. On that same day it was also voted that Daniel Kelsey should have leave to set his house six or seven feet into the street.
The record of his alleged second marriage to Eunice Jarvis at Huntington, June 1, 1724, refers to him as being "of Norwalk in Conn.," and he may have moved across Long Island Sound for a time. He was living at Huntington at the date of his third marriage, December 16, 1750. The baptisms of his two sons by his second marriage, and the marriages of all his children, are recorded in the Huntington church records.
The will of Daniel Kelsey was made September 3, 1750 and reads:
"In the name of God Amen - I, Daniel Kelcey, of the town of Huntington, cordwainer, being of sound mind. I leave to my son Stephen all my lands , meadows and buildings, and my team, cart, and tack-ling and farm utensils, and he is to pay my son Jonathan £60 and to my granddaughter, Keziah Kelcey, daughter of my son, Timothy, £65. After payment of debts, I leave to my son Daniel 1/3 of all my movable estate, and to my daughter Mary, wife of Ananias Brush, 1/3. I make my friends and neighbours, Eliphalet Wickes, John Wickes and Moses Scudder, executors. /s/ Daniel Kelsey"
The will was witnessed by Nathaniel Wickes, John Wickes, and Ebenezer Prime. It was proved October 16, 1752.
He was instrumental in developing the oil industry. Benjamin Silliman Jr.’s primary contribution to the chemical world, and certainly the world as a whole, involved the fractional distillation of petroleum, analyzed mainly for the purpose of its qualities of illumination. He was asked to do this as one of the most prominent chemists of his time, and his report on the subject afterwards had extremely far-reaching influences. The immensely important main idea of his report was that distilled petroleum burned far brighter than any fuel on the market, except those that were far more expensive and less efficient. His conclusion was that petroleum is “a raw material from which...they may manufacture a very valuable product.” Silliman also noted that this material was able to survive through large ranges of temperature, and the possibility of it being used as a lubricant.
His father Benjamin Silliman Sr., also a famous Yale chemist, developed the method of fractional distillation that enabled the economical production of kerosene. Benjamin Silliman Sr. was clearly the largest inspiration in Benjamin Silliman Jr.’s work. Both Sillimans were eminent chemists and professors of the subject at Yale University in their day. The father was the very first professor of chemistry at Yale in 1802, and studied the subject at the Medical College of the University of Pennsylvania. He was also the professor of as natural history - which was defined as geology, mineralogy, zoology, and botany, all of which he studied at the University of Edinburgh. His work in these areas established Yale’s rock and mineral collection as the most renowned and significant in America at the time. With his help, Yale was considered to be the foremost center of science in 19th-century America, and Benjamin Silliman Sr. is considered by many to be the father of American chemistry.6
