"... Phillip Meister, possibly born in Milwaukee to a Simon Meister. He eventually married an Elizabeth Schneider, ..."
There was a Johann S. Meister who died in Milwaukee in 1867. He was married to a Margarethe. There were multiple death notices and other brief clippings in 3 of Milwaukee's German papers at the time. They may reference a son Philipp (German spelling ;-)
There are about 125 occurrences of the name Meister collected in "Milwaukee's German Newspapers; an index of death notices and related items" (1844-1950).
