Sorry for the delay on getting back to you. My name is Franz Valla and I am a Brazilian journalist living in New York. My grandfather has the same name as mine and went to Brazil in a youngage. His name was changed to Francisco Vala once he got there. He traveled with his brothers Johan and Wenzel Valla who became Joao e Wenzel Vala. The later did not had any kids but my grandfather and Joao had several sons and daughters. My grandfather was born at the chec republic but held a german passport once he arrived in Brazil.
