WHAT I KNOW ABOUT GERHARD BARTELS:

• He was born in Vynen, Germany in 1832.
• He emigrated to the USA with his younger brother, Ferdinand, in 1867 aboard the ship Cimbria, travelling from Hamburg to New York City.
• Eventually both Ferdinand and Gerhard made their way to Milwaukee, Wisconsin.
• In the above document (Gerhard's marriage to Anne DeLeslie in 1869), Ferdinand and his wife Mary are witnesses to Gerhard's wedding.

I cannot find any record of Gerhard or Anne DeLeslie Bartels after this marriage in 1869. Does anyone have additional information about his whereabouts after 1869? I've searched the 1870 census extensively but cannot locate him. And I do not know if he stayed in Milwaukee or moved elsewhere.
