So far I am the only one I know of in my family that has done the O'Flaherty/McKee chart. I am continuing work on the charts from the other side of the family, and so it seems fairly easy to just follow the pattern that I have been shown by my Grandmother. This chart is my work and I expect there are errors. It is only a humble beginning. It is the very least I can do for such a great family with a great history.
