Genealogy / Information on last name Geras [12]

I know. Too old thread but let me contribute.
The family Giera and it's variances like GERAS, Gera and Guiera are found in south of Brazil.
In 1878 arrived in São José dos Pinhais, Brazil from Poland, Szymon Giera wich name was written as Simão Geras. His descendents have their surname written in a wrong way like Geras, Giera, Guiera and Guerra wich means War in Portuguese.

I'm looking for informations about Giera family.

Best regards

Anderson Guiera
