Fredrick Holl is the 2nd great grandfather that I know the least about. He was born sometime in 1858 (maybe April) in Prussia. When he was a teenager, he came to the United States and at roughly age 25 he married Carolina Lindor. They had 6 children — 5 daughters and 1 son. He died sometime after 1930.
Over the years in Wisconsin, he looks to have worked various jobs, including a coach cleaner on the railroad, a factory worker and a farmer.
