By Hereditary Virtues: a History of Lough Rynn

Hardback, 2020 edition.

‘Lord Leitrim was not a bad man – if he got his own way’  


So one contemporary writer described William Sydney Clements, the 3rd Earl of Leitrim. The Earl lives in local memory as a notorious despot who represented the worst excesses of landlordism in Ireland during the 19th century.

About the book

Drawing on various primary and secondary sources, By Hereditary Virtues describes how the Lough Rynn estate emerged from early times up to the end of the 19th century. It focuses largely on the 3rd Earl of Leitrim including, his management of the Lough Rynn estate, his role during and after the famine and his eventual demise. 

In doing so, the book provides evidence to support the long-held characterisation of Lord Leitrim as a tyrannical landlord. It also explores evidence and perspective that provide new context and perspective. Here was a man who started with a strong determination to improve the land and the lives of those who lived on it, but who ultimately destroyed and was destroyed because of his arrogance and hubris.  The story, however, is not just about one man, but rather about all the people who lived and died during an important period in Irish history. 

The 2020 edition includes includes additional research on the famine and post-famine era and a new chapter on Lord Leitrim's relationships with the women in his life.

This is the classic local history, a scholarly mosaic of political, social and cultural life which is marked by lucidity, elegant prose, [and] sharp psychological and social observation. We need this kind of intelligent, analytical history.’  Professor Michael L. O'Rourke, Trinity College Dublin

A real treasure

A real treasure, that I'll come back to time and again. Fiona has that rare gift of balancing diligent research with engaging story telling. The wonder of this book is that the reader gets lost in the drama of the day, and picks up a rich historical understanding as a by-product.

An excellent read

Being from the locality I thoroughly enjoyed reading and learning about the history of Lough Rynn and the Mohill area, much of which I was not fully aware of. Lough Rynn has always been a special place to visit. By hereditary virtues allows the reader to visit Lough Rynn in way that lends a greater appreciation for the history of the place and of the lives of the people of the area.

A MOST rewarding read; insightful and erudite. Research has been developed into remarkable prose and first-class writing. This is a book that is not just of local interest, but is truly of national relevance.

Informative and well presented. A wonderful read.

I purchased 'By hereditary virtues a history of Lough Rynn' to give me further insight into life on the Lough Rynn estate. I discovered that my 2nd Great Grandfather and his family lived and worked in the Farnaught/Mohill area. Our family burial plot is located in St Mary's Churchyard Farnaught. Having stayed in the Lough Rynn Hotel on a couple of occasions to research ancestry, I found Ms Slevin's writing informative and well presented. A wonderful read.
