"... The Zenkers in Millwakee are related to us by way of cousins or uncle to my grandfather ..."
In case it's helpful to your research, a Paul Zenker (54 yr., survived by Anna) died in 1919; a Robert Otto Zenker (2 mo.; parents Robt. & Selma) died in 1893; Friederika (Zenker) Mueller's husband John died in 1929. These families placed death notices and/or followup thank you notices in Milwaukee's German language newspapers.
"Milwaukee's German Newspapers; an index of death notices and related items" (1844-1950).
Brushing of the dust of neglect and misinformation about Milwaukee's German newspapers since 2007.
