Whitney

Sk,

You do not indicate the years you are researching. I attach a copy of the Tithe record for Aughamore in the parish of Columbkille, Granard, Co. Longford 1823 which has a number of "Whitney".

The records can be accessed for free at  www.nationalarchives.ie/geneology

According to Dr. Edward MacLysaght the surname is in Leinster since the 14th century and comes from a place in England. 

If you check Griffith's Valuations - 1846 - 1860 for property holders at  www.askaboutireland.ie and the Irish census for 1901 at www.nationalarchives.ie/census  Both are free Sites, you will get more recent records.

Regards,
