The Hession family motto is "Wish nothing base".
Hassan may have an eastern look but in Ireland it is the anglicized form of Ó hOsáin. It is to be distinguished from Ó hOisín and Ó hOiseáin (see Hession and Hishon). In County Londonderry, where it is numerous, it is spelt Hassan, Hassen and Hasson. In the Monaghan Hearth Money Rolls of 1663 it appears as O'Hassan. There was a Hasson of Wexford among the "principal gentlemen" of that county in 1598, but that family was no doubt of non-Gaelic stock and a John Hassan was an influential merchant in Wexford fifty years earlier.
