Island Pond (Rockingham County, New Hampshire) Island Pond (Rockingham County, New Hampshire) Island Pond (sometimes referred to locally as Big Island Pond) is a water body located in Rockingham County in southern New Hampshire, in the towns of Derry, Hampstead and Atkinson. The pond is near the head of the Spicket River watershed, which feeds the Merrimack River in Lawrence, Massachusetts. The pond was formed from the merger of two smaller bodies of water in 1878, when a dam raised the water level by 8.5 feet. The pond is named for Governor's Island, a island that lies within it. The island in turn is named for
Justinian of Ramsey Island His more loyal monks followed him. Legend has it that he was eventually murdered by some disgruntled servants or monks fed up with his strict regime, it is said by beheading him. Apparently he picked up his head and crossed Ramsey Sound walking on the water carrying his head in his arms and his body was buried in the small ruined chapel which still stands on the mainland at St Justinian's, immediately opposite his island home. Justinian is listed on very ancient Welsh calendars of saints and martyrs and the Anglican church at Llanstinan, near Fishguard, is dedicated to him.
