Tighfield was a village or town located somewhere in the Shire. It was the home of several families, specifically Gamwich (later Gammidge) and Roper families.
Wiseman Gamwich came to Tighfield about two hundred years before the War of the Ring, and Wiseman's son Hob Gammidge is recorded as a roper, one of a long line of Tighfield rope-makers.
Hob's son Hobson, and in turn his son Andwise, were said to have practised their craft in a rope-walk (that is, a rope-maker's yard) for many years.
Hob's grandson was Hamfast Gamgee, Sam's father, who left Tighfield for Hobbiton, to start a new life as a gardener.
