Thank you Michael, Lindel, Bob, Boyd and Ray. I have downloaded and read the pdf that explains Griffith's. Now I know what "Office" means! I realize that reading may not be the correct word to use -- studying the document might be more appropriate. The recent postings about maps on this list rekindled my desire to locate that piece of land in Donegal once occupied by ancestors. Long ago, in my own narrative of my Sutherland line I wrote 'An 1829 list of landholders of Redford-Glebe shows slightly more than 14 acres belonging to "Widow Kearney & Michael Sutherland".' This information is consistent with the information found on Lindel's page http://freepages.genealogy.rootsweb.ancestry.com/~donegal/cloncatab.htm <http://freepages.genealogy.rootsweb.ancestry.com/%7Edonegal/cloncatab.htm> My information came from the late Brian Bonner, a writer and local historian who published several articles in the Journal of the County Donegal Historical Society. He sent me an unpublished (at least as of the time he sent it) manuscript titled "Redford -- Glebe: The Story of an Ulster Townland". The information came from a table in the manuscript (manually typed, not scanned and pasted). There is another table in the manuscript in which Brian referenced Griffith's. The table heading reads "The land occupiers and residents in 1857 were:" Under the column headed "Observations" Brian wrote "Dwellinghouse and offices. Unoccupied. Former tenant Sutherland." Later in the manuscript is written "The farm occupied by Sutherland was later amalgamated with that given to John McLaughlin." When I search Griffith's/Donegal/Inishowen for Sutherland there are no hits. However I can view the listing for Redford Glebe and see "Unoccupied" just beneath the name "John McLaughlin". So I am seeing this latest activity as a success: I have located a place that was probably occupied at one time by my ancestor -- and for that I thank each of you who has helped in this quest. However, I say "probably" because I am still uneasy about Brian's statement "Former tenant Sutherland". Where did that little piece of information come from? It's not in Griffith's. So my final question: does anyone know of another source where Brian may have seen or concluded "Former tenant Sutherland"? Thanks again for the prod to get me going and the answers and directions you provided. Bob Sutherland
