Did you read the book : The Elusive Eden- Frank McMullan's Confederate Colony in Brazil, by William Clark Griggs ? There were several reasons for the immigration of the ex-confederate soldiers to Brazil ! My ancestor's surname appears with Wingutter.
We have today in Santa Bárbara D'Oeste, São Paulo, The Feast of Confederados, in Second Sunday of April ( seven days this year ) is celebrated with dances and clothes from the period preceding the war.Meals are also typical of the southern U.S. We have also the Confederate Cemitery, where soldiers are resting ! Jimmy Carter visited him with his wife Rosalynn years ago !
Please, send me your e-mail !

Thank you !
