place in West Yorkshire, late 11c., from Old English halh "secluded spot, nook of land" (cognate with Old English holh "hole, cavity") + feax "rough grass," literally "hair" (from Proto-Germanic *fahsan). In popular expressions coupled with Hull and Hell at least since 1620s. "In the 16th cent. the name was wrongly interpreted as OE halig-feax, 'holy hair', and a story invented of a maiden killed by a lustful priest whose advances she refused." [Victor Watts, "English Place-Names"]
