Super pics, thanks for posting. Looks like you had an excellent time and I'm glad you got better weather than we've been having here in Scotland lately.
My maternal grandfather's side also has Dutch ancestry, going back to one of King William's troops who came over to fight in the Battle of the Boyne, fell in love witrh an Irish lass and stayed behind. There are still some Mewhorts in Northern Ireland, (my mother's maiden name), though most seem to have found their way to Canada.
