The Drishane estate of the McCarthy's was forfeited in 1641 and was never restored. The Drishane chief at the time was Donogh and a source gives his life-span as 106 years 1619-1725. In 1645 besides the Drishane McCarthys now dispossessed there were five other McCarthys in the parish, one of them at Kilmeedy. After 1641 a son of Donogh settled in Dooneen across the Finnow river and this branch of the family during the following hundred years managed to maintain something of its old position and one member at least achieved some distinction with Clare's Irish Brigade in France. During the latter part of the 18th. century the owner of this estate was Denis McCarthy known as Denis of Glyn born 1731.2 0
A digression is necessary at this point to explain the merger of the McCarthys now in Dooneen with the O'Leary family of Coomlogane. The O'Learys of Coomlogane were a subsidiary clan of the McCarthys and had caused the latter considerable trouble from time to time. One of them, General Arthur O'Leary, who married an aunt of the Liberator, Eileen Duv, and who was killed at Carriganimma in 1773, was the subject of the greatest elegy in Irish Literature. Arthur had been a General in the Austrian army and a friend of the Empress Marie Therese who sponsored some of his children.
The circumstances of his death (are as follows). He spurned the offer of £5 for his horse after a struggle in which Eileen helped him to beat off his attackers from his house and was subsequently shot at Carriganimma.
The O'Leary head of the clan died towards the end of the 18th. century and his only daughter Eileen succeeded to the estate. There was trouble and a lawsuit about succession. It was claimed that Eileen O'Leary was illegitimate and therefore could not inherit the estate.2 1 Her father, it was said (legend) was keeping company with a girl from Rathmore who was the mother of Eileen. By this time, as we have already seen, the representative of the McCarthys of Drishane dispossessed after 1641 and now in Dooneen, was Denis born 1731 (circa) and known as Denis of Glyn. His son, another Denis, succeeded to the O'Leary estate in the following manner. His mother died in 1780 and his father married secondly Eileen daughter of the O'Leary of Coomlogane.2 2 There were no children of this marriage so that Eileen O'Leary willed the property to her stepson, Denis McCarthy, on condition that he add an "O'Leary" to the family name. Hence the McCarthy family of Dooneen, now of Coomlogane merged with the family of O'Leary and became the McCarthy O'Leary family, residing at Coomlogane.2 3
This may be the Denis of Coomlogane mentioned in the family tombstone who died 1825 aged 80 years i.e. born 1745. 20
A man (legend again) swore that he saw O'Leary and Eileen's mother being married secretly in the old church in Rathduane. Q. What old church? Does it go back to 1800? 21
2 2 The Eileen already mentioned?
