The primary valuation of Ireland or Griffith's Valuation - carried out between 1848 and 1864 to determine liability to pay the Poor rate (for the support of the poor and destitute within each Poor Law Union) - provides detailed information on where people lived in mid-nineteenth century Ireland and the property they possessed. It can be found on various websites.
Below is the segment for the villages of Creeveroe Davies and Creeveroe Ffrench. The Matthew Crehan who is shown in Creeveroe Davies could be the same Math Crehan given as the father of my 2nd great-grandad Thomas Crehan on Thomas's marriage certificate of 1873, which also shows that Thomas came from Creeveroe Davies, then called Creeveoe Cornwall. Thomas Crehan's marriage certificate of 1873 shows that his wife was Catherine Dowd of Creeveroe Ffrench, daughter of Patrick Dowd and there are two Patrick Dowds shown in Creeveroe Ffrench here on the valuation of 1855. I have not included the salaries and rents.
The Ffrench family
The Hon. Martin French who was the main lease holder and land lord of the villages of Creeveroe Davies and Creeveroe Ffrench as shown above, was undoubtedly a member of the same Irish family surnamed Ffrench/French from whom came Sir John French who was the commander of the British Expeditionary Force in 1914 during WW1 and for whom their is a brief mention in an exhibit in the Galway City Museum as shown in the picture on the left. The Irish French family were a branch of one of the Tribes of Galway as explained in the exhibit pictured left.
