Hi Janet Since Griffith Valuation took place after your Gregorys left Co Tyrone, I checked out the tithe applotment books, where I found the following Gregory listed: 1827 Francis Gregory, Mullabane, Carnteel 1828 John Gregory, Lower Gils, Camus 1832 James Gregory, Killlymorgan, Errigal Keerogue 1833 James Grigory, Killymorgan, Errigal Keerogue. You will note that in 1833 James Gregory has become James Grigory. I noted too in other counties many where the surname was also spelt Greggory as well as Grigory. Looks as if it's worth checking out surname variants whilst searching.
