De Burgh (Dromkeen)
- This family of Bourke originally from county Mayo settled at Dromkeen in county Limerick in the 15th century. In 1726 Thomas Burgh of Dromkeen, son of the Reverend Richard Burgh, married his cousin Mary Burgh of Oldtown, county Kildare and they had a son Richard who died in 1762 and left his estate to his cousin Walter Hussey later Lord Chief Baron of the Court of Exchequer in Ireland. Richard's sister Mary married Philpot Wolfe of Forenaghts, county Kildare, and appears to have inherited land in county Limerick. Walter Hussey de Burgh held land in the parish of Dromkeen, barony of Clanwilliam, county Limerick, at the time of Griffith's Valuation. His estate appears to be connected to that of the Balfes. His son, John Hamilton Hussey de Burgh, married Louisa Townsend, of Shepperton, county Cork and is associated with property in that county.
Members of this family were still residing at Dromkeen in the 1970s.
