What is meaning behind the name Hancock Glen

glen is a valley, typically one that is long and bounded by gently sloped concave sides, unlike a ravine, which is deep and bounded by steep slopes. Whittow defines it as a "Scottish term for a deep valley in the Highlands" that is "narrower than a strath", The word is Goidelic in origin: Gleann in Irish and Scottish Gaelic, glion in Manx. The designation "glen" also occurs often in "place names".

Happily enough, my father's name was Glenn, my wife's name is Glenna both of which have roots from Gleann, which is a type of natural landscape called valley or Glen.  We live in Westchester Meadows in Grand Prairie, Texas on a street named Sleepy Glen.
