The O’Gradys (0 Grada) were an important Dalcassian family in
County Clare. They were originally seated in the parish of Killonasoolagh, near the River
Fergus in South Clare, but after 1318 they obtained a wide territory around Tomgraney in
the north of that county, from their O’Brien kinsmen and patrons. This territory
embraced several parishes in Clare and Galway. In 1543, Donogh O’Grady, "captain
of his nation," was knighted by Henry VIII, and formally granted the lands of his
clan. After him, the heads of the O’Gradys served the English interests, and some
Anglicized their name as "Brady," though this was an alias and usually the form
"O’Grady" was resumed. A branch of the family settled in Gonnacht, while
the chief family settled in Limerick several centuries ago.

of Glontarf, who fought against the Vikings in 1014 (see under O’Brien, above). The
