I'm researching the past of my lost Grandfather. His name is Johannes Albert Martin Berger. He was born on November 9, 1895 probably in Hamburg. He emigrated between 1926 and 1929 to the US. He married in Chicago in 1932 but was divorced in 1933. He was a bank clerk. I haven't found anything in the 1930 Census. So I wonder if this name rings a bell.
