Looking for information on two sibligs:

~Augusta Manzke/Munzke (b.Apr 1863 Germany - d.1928 Minnesota) married Wilhelm Nitz prior to immigrating to the US in 1892

~Carl Manzke/Munzke (b. around 1854 Germany - d. ???? in US)

According the the US census of 1920, Carl was living with nephew Emil Nitz (Augusta's son) and his family.

Any information of Augusta and Carl would be greatly appreciated.

Thank you.
