There are six families of Kellerman's in Oshkosh, on the 1900 census.
Aloyius and his family.
John, son of Aloyius, and his family at 281 Eighth St.
The Frank Kellerman family at 440 Sixth street. Frank (1855), his wife Anna (1856), their children Mary, John, Julie, and Kate. They arrived in 1893 and all were born in Bohemia but Kate. No connection yet.
There is also the Frank Kellerman family living at 461 Tenth street. Frank (1867-?) and his wife, Marie (1870-?), live with their children Laura (1891), John (1895), Maggie (1897), Willie (1899), and a son-in-law, Frank Pable. They all claim Bohemia. I do not have a connection to Frank Kellerman at this time.
There is also the Mike Kellerman family living at 503 Tenth street. Mike(1855), his wife Mary (1867), their children Frank, Katie, Joseph and Mike. They claim Germany as a birthplace. No connection yet.
And then John Kellerman who arrived in America in 1872 from Germany. He lives at 163 Sixth St. with his children: Anna, Louis, Therese, Simon, and grandson Frank. He is widowed. All children were born in Wisconsin. It is interesting about Simon that at age 16 his occupation is bartender. I do not have a connection to John Kellerman at this time.
