Bibliographic Details
Main Creator: Longfield, John, ca. 1775-1833, surveyor
Contributors: Longfield, William, fl. 1825-ca. 1870, surveyor
Format: Manuscript
Notes:The company was based at Grafton Street, Dublin, until 1825, when they moved to 19 Harcourt Street, Dublin.

Arranged by County and Barony. The catalogue gives the full title of the maps in addition to dates and the name of the surveyor where available.

Maps were sometimes drawn on the reverse of earlier printed maps and as a consequence it is unreliable to use the paper's watermark to estimate the date of the map.

John Longfield was trained by Peter Bernard Scalé (1739-1826) who had in turn been trained by John Rocque (ca 1704-1762). Rocque had established the French School in Ireland.
