William's son Thomas provided the following information about William in a published biography, extracted and transcribed by Linda Berney:
....[Thomas'] father, [William] was a watchmaker by trade, which he followed in the early part of his life. He came to America in 1753, located in Suffield, [Connecticut] and subsequently removed to Bennington county, Vermont, where he became the owner of about 150 acres of land and where he spent the rest of his life in agricultural pursuits. He died in 1830 [sic] at the age of 96 years. He was twice married. By his first wife, Lucy Buck, he had 9 children, and by his second wife, 6, the subject of our sketch being one of the later. The second wife was 84 years old at the time of her death. They were all Episcopalians. During the Revolutionary war William Imus was 3 times drafted into service, but would not fight against his own country and relations, and each time hired a substitute. The paternal grandfather of our subject was William Imus. He was the father of four sons, and was a large property owner. He lived and died in England.

From other research by Linda Berney:

As a young man in Connecticut, William was reportedly arrested and confessed to counterfeiting. Because he became a witness for the King, he was not prosecuted. He owned land in Connecticut, including some inherited from his father-in-law Joseph Buck. William and Lucy were living in Connecticut at the outbreak of the Revolutionary War. As indicated in his son's biography, he was a Loyalist, and was arrested for treason and held in irons for 3 months. Upon his release he joined the US Army in New York and served as an armorer and recruiter. In 1786 William filed for claim as a Loyalist for his imprisonment, but was denied.

As mentioned in his son's biography, he acquired land in Bennington County, Vermont, where his will was probated. His second wife's name was seen as Anna Rising or AnnaTolbert. Perhaps one is her maiden name and the other from a first marriage?

It should be noted that some sources indicate William's father, who remained in England, was Joseph, rather than William, as indicated by his son Thomas.
