Eli Phelps was a prosperous tobacco farmer in Windsor. Around 1860 he built the impressive Italianate house that stands at 18 Marshall Phelps Road in Poquonock. As related in the Commemorative Biographical Record of Hartford County (1901):
Hon. Eli Phelps was born at Poquonock, Sept, 1, 1807, and had only such educational advantages as the local schools of that day provided. He was but a young man when his father died, and as the only son the care of the estate fell to him before he had a chance to acquire business experience, yet he managed affairs with conspicuous ability and became one of the most successful farmers of the town, obtaining good results under all circumstances. For some years after his marriage he resided at his father’s old home, later locating at the farm now occupied by our subject. While he left a handsome estate to his children, he was never grasping or unduly economical, and many worthy enterprises were helped forward by his liberality. He was a man of fine physique, six feet tall, weighing 200 pounds, and his mental ability was above the average, his reading and observation enabling him to gain a wide range of practical knowledge. He took an active interest in religious work, serving as treasurer of the Ecclesiastical Society of his town for a long time, and politically he was prominent as a member of the local Democratic organization. At various times he held offices in his town, and for several years he was a member of the General Assembly. He died Sept. 1, 1879, and his remains now rest in the cemetery at Poquonock.
