Richard U. Deneault

Richard U. Deneault, 86, died at Merrimack Community Hospice on Tuesday, September 29, 2026. He was the beloved husband of Collette E. (Roussell) Deneault, with whom he was married 38 years.

He was born in Lebanon, NH on February 24, 1940 and was a son of the late Rena (Reney) and Romeo Deneault. He received his education in Enfield, NH and was a graduate of Enfield High School.
