I am tracing the Hallof family from the Banat region (now part of Romania, Serbia and Hungary). Mary Hallof came from Saint Hubert in 1914 with her parents Josef and Elizabeth Hallof. She was my grandmother's first cousin.
Mary Hallof married Peter Exner. Peter came from what was then called Yugoslavia in 1905. At the time of the 1930 census they were living in Chicago and Mary was 27 years old and Peter was 29. They had a daughter named Rose who was 8 years old in 1930. I'm looking for any further information on this family. Mary Exner died in 1977 in Illinois. Rose's children (if there were any) would be my third cousins.
