It's wonderful you've managed to find the naturalisation papers of your great-great grandfather!
The name Caprohollow does not ring a bell, and I wasn't able to find anything in the church records
, or on the list of townlands
. It is possible that the name has changed throughout the years, or that it was written phonetically when your ancestor arrived in the US. Around what time did he live on the island, and could you perhaps share a scanned copy of the document here? It might give us some additional clues. :)
I hope you'll receive more tips and suggestions from our experts so you're able to find this missing piece of the puzzle!
