Hi Tanman,
I was just wondering how sure that your gt grandfather came from Kells, Meath. The reason I ask is that Kells is prominently an Ulster surname, for example if you search under the 1901 census the vast majority are from Ulster, with the those that are outside Ulster mainly in Dublin. There are only 2 male Kells in County Meath in the village of Oldcastle. If your information is from the shipping records could it be possible a) that he was from Kells, County Meath and because his name was difficult to pronounce or for some other reason gave the name Kells or b) Could it be that the enumerator copied the name or town twice in error. So I guess my question is do you have a record of your gt grandfather in Kells, Meath with the name Kells?
By the way there is also a Kells in County Antrim.
Good Luck
Gerry
