There should be scepticism about all sources, books tend to be more researched and responsible, website less so.
Usually there is more than 1 meaning to a name, 2 or 3 names often running into common spelling.
An example is KELLY (my mam's side), there were 3 sources for Kelly, all slightly different, we being the Derry Kellys spelt Ua Ceallaigh
Anyone know the history behind the Ua, or is it an Ulster Ó?
