Griffith's Valuation is a property survey that was conducted in Ireland between 1847 and 1864. Since census records prior to 1901 do not survive for Ireland the survey is used to get an idea of how the Ferguson were distributed in Ireland circa 1858. The map below shows how the 45 different Ferguson households were distributed within the county Leitrim.
Consistent with Griffith's Valuation the parish with the most Ferguson households is still Rossinver with Cloonclare a distant second. Two of the lines from parish of Rossinver have been DNA tested, one from Largydonnell and one from Tullyskeherny. Both testees are Haplogroup R-M222 which is often referred to as "Northwest Irish". The lines tested are highlighted in the table below. .
