My grandgrandfather's name was Karl MISCH. He was 14 years old when he came to Brazil about 1875, and he died in April 1911, in Curitiba. Here he married ALBERTINA SCHILLING, who came from Germany, also. I didn't find any register on their entries with those surnames - Mish and Schilling. I found 5 (five) MISCHKE registrations, here in the state of PARANÁ, southern Brazil. Do you know is there any possibility their surnames have changed form Misch to Mischke ?
