My grandfather and his brothers came to the US from Sweden between the 1860s and 1880s. Because of pay packet mix-ups in the Michigan mines they changed their surname from Nilsson to Ljungberg, but the non Scandinavian residents couldn't spell or pronounce it correctly. The brothers then changed Ljungberg to Youngberg which was close to the original Swedish pronunciation. In Swedish "ljung" means "heather/ling" and "berg" means "mountain/hill". This type of name change was not uncommon even in Sweden when the patronymic system was still in use. Young men entering the army would often change their surname to a non-patronymic name such as a place name or geographical feature to avoid confusion.
