I have done a great deal of research in microfilms of the Albert Casey works covering the Upper Blackwater areas of Cork and Kerry. There are 8 films of this 16 volume series - the first 14 are on the eight films and the last two books in the series are not available. I have extracted almost every Pickett and variation for this area, and that includes families in Kerry.
