I am curious whether anyone knows if K/Cavanaugh vs K/Cavanagh is any indication of a particular county? My grandfather always said his father was from Cork, while this may have just meant he left from Cobh, I see more K/Cavanagh data listed on the Cork list then K/Cavanaugh. I would not have thought that the immigration people would have thought to put down Cavanaugh instead of Cavanagh. Or am I just overthinking the difference? Unfortunately my great-granfather was born in Rhode Island not Ireland but his father was from Ireland. Rick Shea
