Best Answer - Chosen by Asker: Gray

1. English: nickname for someone with gray hair or a gray beard, from Old English gr㦧 ??gray??. In Scotland and Ireland it has been used as a translation of various Gaelic surnames derived from riabhach ??brindled??, ??gray?? (see Reavey). In North America this name has assimilated names with similar meaning from other European languages.

2. English and Scottish (of Norman origin): habitational name from Graye in Calvados, France, named from the Gallo-Roman personal name Gratus, meaning ??welcome??, ??pleasing?? + the locative suffix -acum.

3.French and Swiss French: habitational name from Gray in Haute-Sa㴮e and Le Gray in Seine-Maritime, both in France, or from Gray-la-ville in Switzerland, or a regional name from the Swiss canton of Graub㼮den.
