Not sure if they are related, but a relative of mine married a Anton Kreutzer in Milwaukee Dec 17, 1870. His father is listed on the Marr. cert. as Anton and the mother as Eva Langstein. A book of names indicates that Andrew and Anton may be the same, or both a variation of Tony. The person he married had her 1st husband die in 1870, they ran a tavern in Milwaukee. Anton then helped run it.
The 1880 census indicated his name as Antone Kereutzer,
age 34, born Hsse Damstadt (his parants also born there),
occupation beer brewer. His wife was Anne (Johanna) Schulz (nee Schlegel). She was 44 yr. old in 1880 census. She died in 1909 and her name on the gravestone was Johanna Kreutzer. Unknown what happened to Anton. More info. may be available. Will check for possible additional info. if you are interested.
