re: The will of Thomas WHITNEY, Newpass alias Derrydown (Derrydooan), co. Westmeath Ireland, 30 April 1740
mentioned his brother BOLEYN WHITNEY,
his sister Ann Upton & her husband Ambrose Upton,
his brother Shuckburgh Whitney.
Thomas WHITNEY's lands, etc., were "castles, towns and lands of Newpass, Rathowen, COLEMORE, COLEBEGG, Win(d)town, Ballygarron, Ballydorey" and others in Co. Westmeath.

Boleyn WHITNEY was nephew of Mrs. Robert Adair of co. Longford, houses in Dublin City, and of "Hollybrook" co. Wicklow, mentioned in Mrs. Adair's will of 1747.

Would the tune "Johnny Adair of Derrydown"
be John Adair of Derrydooan (who may also have
had properties in co. Longford just to the east) ?
