Estate Maps
Lynch-Blosse & Garret Moore Estates
This collection of estate maps was found in Balla Secondary School, formerly Athaville House, by the principal Mr. Patrick Sheridan and for over a century prior to that had been considered lost or destroyed. They were very generously entrusted to Mayo County Library who undertook to conserve them and digitise them in order to make them available over the Internet. The maps cover an area ranging from Balla to Lough Mask and Lough Carra and extending eastwards beyond Claremorris. The maps that belonged to identifiable sets have been grouped together as described below and the remainder have been grouped under the heading of miscellaneous
The Lynch-Blosse collection of estate maps contains:
- Maps of Sir Robert Lynch-Blosse Estate in the Barony of Clanmaurice 1811 This is a complete set of 38 maps, produced by Sherrard, Brassington and Greene, Dublin, 1811. Drawn to a scale of 16 perches to 1 inch. Each map has it's own reference sheet, listing the tenants in the townland and describing the quality of the land.
- Maps of Sir Robert Lynch-Blosse Estate in the Barony of Clanmaurice 1819.This set contains maps of just three townlands in the Barony of Clanmaurice, redrawn in 1819 from the 1811 set. The most interesting feature is that the re-survey was carried out by William Bald.
- Maps of Sir Francis Lynch-Blosse Estate in the Barony of Carra . Produced by Clarges Greene, Dublin, 1830. Also drawn to scale of 16 perches to 1 inch and again, each map has it's own reference sheet describing the land in the townland. The complete set consists of 47 maps. Map no. 1, Castlecarra, was originally surveyed in 1811.
- Miscellaneous Maps of Sir Robert Lynch-Blosse Estate There are 15 maps in all, the first is numbered 2 and the last 31. Unfortunately there is no indication whether there were any further maps in the sequence. In addition, as there are three different surveyors, it is unclear whether there were three separate collections or just one compiled by different surveyors. The surveyors were Patrick Moran, H. Joynt and Sons, Ballina, and Nolan and Shanley. The scales are 16 perches to 1 inch on some of the maps and 20 perches to 1 inch on the remainder. The surveys were carried out from 1856-1858. The reference sheets for each map list tenants and describe land quality.
- Maps of the Garret Moore Estate
These maps were found with maps of the Lynch-Blosse Estates. The introduction to this set of maps states that they are a copy of originals deposited in the Office of the Chief Remembrancer of the Court of Exchequer by Garret O'Moore in accordance with an order made in conjunction with a court case in which Sir Francis Lynch-Blosse was plaintiff and Garret O'Moore and others, defendants. The maps were drawn to a scale of 40 and the surveyors were Francis Plunkett and Francis McDermott. The date of the survey is 1720/21. The maps include portions of the estate in King's County (Offaly) as well as the Mayo estate. Descriptions of the lands are contained in the references sheets accompanying each of the 40 maps. Map 40 (Bunrevane, Co. Offaly) is missing, relevant reference sheet is available.
