RETTIE is a toponymic surname of local origin from the old lands Reattie or Raittie in the parish of Innerboyndie, Banffshire. These lands were granted to Gilbert de Dun by David II (son of Robert de Brus) in 1367. Willmus RETTIE was elected to the Common Council of the Burgh of Aberdeen in 1474. The surname remains most common in Aberdeenshire in the North-East of Scotland with past emigration largely to North America. So say the paper records!
