In the Griffith's search I did, the highest concentration of the Keilty spelling was in Tyrone - 21 of 58 hits altogether. Some of these may be the same person occupying different lots but it seems odd not to have any of them there in the Tithe Applotment Books. I don't have a good feel for the accuracy of the Tithe Applotment CD. It's published by the same folks who put out the Griffith's Valuation CD, which is the source for most info on the Griffith's found on the internet. I do know from personal experience that the Griffith's Cd is missing material, sometimes even whole parishes. I assume the same is true for the Tithe CD but I don't know for sure. I just re-checked the CD. I missed a variant, Keelty. There are another 8 of these in Tyrone, from different parishes, a lot from Kildress parish. That's the only difference I see though. John
