Why the Grehans are quite posh.

Patrick Grehan III, Celia O’Bryen’s brother had inherited land in the parishes of Killinvoy and St Johns, barony of Athlone, county Roscommon via their grandmother Catherine Hodson. Their grandmother Judith Grehan (nee Moore) was the great, great, great, great, great grand-daughter of Rory O’More, and Margaret Butler, and therefore related to Anne Boleyn

Rory O’More is sometimes referred to as King of Leix (modern day Co.Laois), but is essentially a clan chieftain. But in Irish terms he is Gaelic nobility, Margaret Butler is the daughter of Piers Butler, the 8th Earl of Ormond. The Butlers are Old English aristocracy, i.e they were part of the Anglo-Norman invasion of Ireland in the C12th.

Patrick’s entry in Burke’s Landed Gentry in 1871 reads as follows:

Patrick Grehan, esq., now of Mount Plunkett, is the son of the late Patrick Grehan, esq. of Dublin ( by Catherine his 1st wife, dau. of George Meecham, esq., and co-heiress of her mother Catherine, dau. and eventual co-heiress of William Hodson, esq. of St John’s, co. Roscommon) and grandson of Patrick Grehan, esq. of Dublin who m. Judith, dau. and eventually co-heiress of Edward Moore, esq. of Mount Browne, co. Mayo (lineally descended from Lewis, the 4th son of  Roger O’More, of Leix, by Margaret, dau. and heiress of Thomas, 3rd son of Pierce, 8th Earl of Ormonde). Through this marriage with the co-heiress of Moore, Mr Grehan of Mount Plunkett quarters the arms of O’More of Leix, and Butler, Ormonde. 

Arms–Or, a trefoil, slipped, vert, on a chief, sa., three escallops, of the first; quartering O’More of Leix, Butler of Ormonde, and Hodson of St. John’s–the family of Hodson of St. John’s, is one of considerable antiquity, and at the decease, in 1829, of the last male heir, Oliver Hodson, Esq., a moiety of the St. John’s estates devolved on the present Patrick Grehan [III], Esq.

Crests–A demi-lion, gu. gorged, with three escallops

Motto–Ne oubliex

Seat–Mount Plunkett, Licarrow, Roscommon

Their is a record of the confirmation of arms to Patrick Grehan III, in 1863

  • National Library of Ireland: Arms of Grehan of Mount Plunkett, Co Roscommon, 1863. GO MS 179: 101
  • National Library of Ireland:  Copy of confirmation of arms to Patrick Grehan (III), Mount Plunkett & St Johns, Co Roscommon, grandson of Patrick Grehan (Senior)of Dublin, merchant, 5 June 1863. GO MS 109: 13-14

To help the trail a bit:

Patrick Grehan Senior married Judith Moore, daughter of Edward  Moore. Edward Moore was a partner with Thady Grehan, Patrick’s father. In some sources, Thady is referred to as Edward’s drayman, they were brewers together. In which case, it is a pretty spectacular case of social mobility, pretty much, the van driver’s lad marrying the boss’s daughter.

Edward Moore’s father, James died in 1741. James Moore’s great grand father was Walter More.

Walter More’s father was Lewis (Lysagh) O’More,  one of four sons of  Rory O’More (Ruairi Caoch O’Mordha) who married Margaret Butler. Margaret was the daughter of Thomas Butler and granddaughter of Piers Butler, eighth earl of Ormond.

There is more detail in possibly one of the most complicated entries in Burke’s LG, for the More – O’Farrells of Balyna
