William Hanry (Wilhelm Hinrich?) Schumacher b. 1859 Hannover

I'm looking for information on my great grandfather William Henry Schumacher.He was born on March 3, 1859 in Hannover Germany.He came to the US in 1872 with his father Henry William (Hinrich Wilhelm?), his younger brother Fred, another younger brother, and an older sister from his dad's previous marriage. As I understand it, his mother was not with them, and may have passed away, but William's death certificate indicated her name was Caroline.I can't seem to find any records of them in passenger lists, but I believe they left to the US from Hamburg.William eventually settled down in Pierre SD as a cattleman, and rancher, and passed away in 1943 in Topeka KS at the age of 84
