Because this was such a short paddle from Ireland to Scotland and there were so many fishing vessels there are not a whole lot of records I know that I've run this problem as well trying to find the hop skip from Ireland to Scotland to England.
If you're still looking for link email me and let me know for some reason Nova Scotia has a lot of those records and there is a huge Allen population there or and macallen/ McAllen good luck
