Hi I had order the original Cancellation Books and had ask for the years that my surname was entered for each year for the area they were living. What a wonderful surprise I got. I was able to figure out several relatives marriage & death dates. In the comment area to the far right (in colored ink) there are dates written it. In most cases they are dates that the person no longer rented the land. For me the dates represented death, immigration and marriages dates. With these dates I was able to order the document I need, cause I had a date that was an "about date". My Maggie Friel took over the land due to the death of her father, then when her name changed due to marriage in one of the years she was listed as Maggie Hammond. I knew at least she had married someone name Hammond. Later I found out it was Johnny Hammond. In later years, someone else took over Maggie's land and when the new name was entered there on the far right comment area was a date. I then sent for her death record using that date. To my surprise the death certification was found and now I have that, too. So I believe for me these records are the biggest help I have found in my Donegal research. I gave those Cancellation records to Lindel and Bob hoping to help anyone in those townlands I had collected. I would ask anyone who does order these records to also send them to Lindel & Bob and maybe someday there will be cancellation records for all townlands. Now that would be a great asset to research. Janice Bob, If you send for one, it is even more difficult to see the colours on a black and white LDS film! However, after a while using them, it becomes surprisingly easy to identify the handwriting and the width of pen strokes, so that you can quite easily tell which revision, which usually indicates a change of tenancy (one name scored out, another written above), is associated with which date in the right hand margin of the book. Thank goodness they did not have computers back then or the revisions would have disappeared under the "delete" button!
