- From the mid 17th century the Comyn family were established at Kilcorney in county Clare. In 1796 Laurence Comyn married Jane Lynch of Barna and bought land in the Spiddle area from his in-laws and from the Frenchs. Beggan states that he bought more land from the Blakes of Drum in 1814. By the time of Griffith's Valuation, Francis and Peter Sarsfield Comyn, sons of Laurence Comyn of Woodstock, county Galway, held land in the parishes of Killannin and Moycullen, barony of Moycullen and in the parish of Rahoon, barony of Galway. Francis Comyn also had an estate in county Clare in the parishes of Drumcreehy, Kilcorney and Rathborney, barony of Burren. Part of the estate of Peter Sarsfield Comyn at Spiddle was sold in the early 1860s to the Morris family. P.S. Comyn bought the Browne estate at Gortatleva in 1860 and resold it to Michael Hennessy of Galway, except for Brownville, in November 1869. Through a marriage in 1871 with the only daughter and heir of Walter Bourke of Carrowkeel, county Mayo, the Comyns inherited the Carrowkeel estate in the parish of Addergoole, barony of Tirawley. In 1878 Francis Lorenzo Comyn was recorded as owning 3,654 acres in county Mayo, over 7,000 acres in county Galway and 1,961 acres in county Clare. Holywell, the Comyn home, and 161 acres in the barony of Corcomroe, county Clare, was advertised for sale by Thomas Gibson, assignee of Thomas Francis Comyn in June 1859. This property was held on a lease dated 1803 from Edward O'Brien of Ennistymon to George Comyn of Hollywell.
The Freeman's Journal reported that it was purchased in trust by Mr. Redington for £1900. Most of the Comyn estate of Woodstock and the Brownville property, with a portion of the Comyn estate in county Mayo, were sold to the Congested Districts' Board in 1902. 757 acres in county Clare were vested in the Board in November 1912.
Blake (Drum, Tully & Gortnamona)
- In his genealogy of the Blakes of Drum, Tully and Gortnamona, Martin J. Blake refers to a grant dated 22 Aug 1677 of the lands of Drum and others in the barony of Moycullen, county Galway, to Walter Blake. A descendant, Patrick Blake of Drum, was Mayor of Galway in 1771 and his eldest son, Valentine, married Anne Burke of Gortnamona, near Ballinasloe. About 500 acres belonging to the Blakes, devisees of Nicholas A. Burke, in the baronies of Leitrim, Longford and Clonmacnowen, were advertised for sale in July 1853. This family of Blakes owned a large estate in the parishes of Killannin, Kilcummin and Moycullen, barony of Moycullen, county Galway, at the time of Griffith's Valuation. In the 1870s Valentine [Fitzpatrick] Blake of Gortnamona is recorded as the owner of 17,335 acres in county Galway though Walford notes that he had died in 1870 and his son, Valentine Blake, born in 1868, was a Ward in Chancery.
- The estate at Gortnamona, near Laurencetown, was originally the property of the Burke family but became a Blake estate through the marriage of Anne Burke and Valentine Blake.
