Roscommon is one of Ireland's smallest counties by population, and its name derives from the Irish - Ros Comain, meaning St. Coman's Wood. Its social history is mainly based around agriculture and it was badly affected by the Great Famine of 1845-47, which resulted in the death and emigration of a huge portion of the population. Its people were active in the Rebellion of 1798 and it was also the birthplace of Douglas Hyde, the first president of an independent Ireland. This book sets out the range of Roscommon genealogical sources available to the family history researcher. It devotes a chapter to each source type explaining what information each contains, and where each record can be accessed.
