I have an old family letter date 1906. (no envelope)..but at the top of the letter it says, " Tonranny Island, P.O. via Oranmore, Co. Galway, Ireland." Can someone help lead me to what this address tells me? Is Tonranny Island a town a parish?? is Oranmore part of this address since "via" is in front of it?? thanks for any help
