There were multiple family death notices and an obit. (of some sort) for Heinrich Saubert in Milwaukee's German newspapers. I've indexed these in the collection "Milwaukee's German Newspapers; an index of death notices and related items". It covers 1844-1950. There's just one other Saubert entry: Eleanor Saubert.
Indexing began in 2007 and continues today. Contact me directly for more information.
