Looking for information on Michael Marx who was born in Germany by 1841 and died in Milwaukee before 1889. [Wife Louisa [Hennig/Henning?] Marx is listed as a widow in 1889]

Son Julius appears to have immigrated to the US in 1883, so Michael may have at the same time. He died in Milwaukee in 1918.

Milwaukee has many Marx's. I assume Michael and Louise had more children than just Julius.
