1857 - GRIFFITH VALUATION:
The Griffith Valuation Records and Maps which were documented in 1857 for the Parish Clondavaddog has turned out to be a handy document for a lot of families, although it is not a Census Record for the 1850’s naming the individuals within the home, it does name the head of the household and the exact location of that person's house where the family would had their land and their home.
There is one small flaw with these maps and that is that you have the pretty cream and red ones which were generally produced 20 years after the Griffith Survey itself was published. Most often, this does not matter as there has been no change in land ownership but occasionally the map simply does not match the 1857 Griffiths Record (attached).
Note: On the original maps the scored out plot numbers are same as from the 1857 Griffith Record attached. The replacement numbers are the updated Plot numbers shown in the revised Maps of 1870’s. I have a few slides put together reflecting both types of maps versus present day Google Map locations, so as to be able to "walk the land".
There are TWO references for Culbertson/Culbert family living in Glinsk, Fanad
1857 (Black and White Map)
PLOT.9 James Culbert – Medium sized House and 5 Acres of land
PLOT.7 Shared Mountain land James Culbertson with Samuel, McCoach, Robert Alcorn, Anne Alcorn and Joseph Poer.
1870’s (Cream and Red Map)
PLOT.9 James Culbert – Medium sized House and 5 Acres of land and Plot 12 which was Joseph Poers
PLOT.7 This later changed ownership to 1c (owner unknown). Plots 7a & 7b (next to Plot 9) still showing as shared land.
What it does tell us, when looking at the revised map in the case of Joseph Poer who has Plot 12 in the original Griffith Map (Black and White) of 1857, Joseph Poer has sold Plot 12 he had in 1857 to James Culbert sometime about the 1870’s (Cream and Red map).
