A large % of Smiths in the USA are German-Americans that switched their surname from Schmitt to Smith to avoid Anti-German sentiment.
In most scenarios, you'd mistake a German-American for an English-American due to them carrying English names, until they tell you of their German heritage.
100% agree. But that does not discredit the origins of the Anglo saxon "Smith" The Germains just wanted to "blend in" with the majority "smiths" & avoid the German Hitler connection
Even the royal family of England changed their german last names to Windsor!
