The name Lynch came from the O'Loingsigh family (the Gaelic spelling), then became O'Lynch in the 1500's and finally just Lynch. They were one of the original "Tribes of Galway" and there is a Lynch Castle in Galway, that now houses a bank. (Picture below is for those of you who have always wanted your very own castle).

Caroline has ancestors that go back to Scotland and the Cameron Clan in the Western Scottish Highlands who fought and lost to the English at the Battle of Culloden in 1746. They fled to Ireland, then married the Irish Millers before coming to America. Her German ancestors, the Dormeyers/Dunmire's came from the much fought over land between Germany and France called Alsace. They left to avoid being conscripted to fight the constant battles between the two countries and arrived just in time for the Revolutionary War. They promptly volunteered!
