## History

Haddam, in Middlesex County, is located in south-central Connecticut in the lower Connecticut River Valley. It is also home to Cockaponset State Forest. It was incorporated in October 1668 as Hadham, but unusually for the many New England towns ending in -ham, the spelling eventually came to reflect the phonetic pronunciation. Haddam is the only town in Connecticut divided by the Connecticut River, and only one of three divided towns along the entire Connecticut River, the other two being Northfield, Massachusetts, and Pittsburg, New Hampshire. Haddam contains five villages: Hidden Lake, Higganum, Shailerville, and Tylerville on the west side of the river, and Haddam Neck on the east. For the first two hundred years of the town's existence, the Connecticut River was a major source of income and transportation. Today, the town of Haddam is a residential community.
The town was named for Much Hadham and Little Hadham in Hertfordshire, England, collectively known as The Hadhams.

    Walks around the feet
    Of the women about you?
