I have German, too. Our branch arrived here near the time, or just after the Civil War. Irish, too, don’t know the year, but it’s a fairly common name. (no “O” in front of it).
Supposedly the Welsh name was once French, but that was during the Middle Ages.
French as in William the Conqueror, 1066 ???
From Normandy, Normans...
Our German are Palatines who Queen Anne sent here, 1710...
