Unfortunately the English think they invented surnames: the Doomsday book refers to the name Totten as a derivative from "tot" meaning a village fool or idiot. The word "totten" is German for "dead"; as in the name of the German punk rock band "Die Totten Hosen (The dead Trousers)" . The East and West Totten and Totten Mountain still exist in Norway. If you follow migration patterns it's easy to see that Totten family migration from Germany to Norway and then to the UK; Scotland, Ireland and then England and the States, is highly plausible. No, I cannot be 100% sure; however, it's a better explanation than anything else I have seen. The only probable way to solve it is to match genomes from families in Germany, Sweden, and the UK. If there is a significant match then the issue is solved.
