Lord Bantry’s Cottage, Glengariff, West Cork, from 1760s.

The Whites were probably of a fairly modest background from Co. Limerick.  By astute management and investment in fishing, smelting, and forest removal a large land bank was assembled by Richard White then of Whiddy island.   On assistance relative to the abortive French landing in 1796 the family were enobled.
