Irish medical families

Irish medical families were hereditary practitioners of professional medicine in Gaelic Ireland, between 1100 and 1700.

Overview
Professional medical practitioners in the Gaelic world of Ireland and Scotland was mainly the preserve of a small number of learned families who passed the profession down generation by generation. This principle was practised by other learned families of poets, historians, musicians, and lawyers.

According to Aoibheann Nic Dhonnchadha:

These kindreds were involved in medical practise over successive generations, and, collectively, were responsible for the organisation and regulation of medical schools, the formation and development of a curriculum, the practical training of students, and the translation, composition and transmission of medical texts. Physicians enjoyed a high legal status in Gaelic society, and were supported by the hereditary tenure of lands that were granted to them by the landowning aristocracy in exchange for medical services ... While the precise nature and effectiveness of the treatment they gave their patients is unclear, the quality of the intellectual training Irish doctors received in their professional medicals schools was high. They were well equipped to offer their aristocratic employers a medical service that was informed by the best of contemporary scientific learning.

The texts
Aoibheann Nic Dhonnchadha writes:

The extensive corpus of medical writing that survives in Irish comprises more than a hundred manuscripts written during the period c. 1400 to c. 1700. These documents, most of which are housed in Irish libraries, are the most important written record extant for the institutional organisation and medical practise of physicians in late medieval and early modern Ireland and Scotland.

Among those that survive are:

 * RIA ms 996 (23 N 17)
 * TCD ms 1372 – partly written by Giolla Pádraig mac Giolla na Naomh Ó Conchubhair
