Schroeder-Schröder: Home page

My data is found on: http://worldconnect.rootsweb.com/cgi-bin/igm.cgi?db=5-hhs which represents my father's family
Herman Henry Schroeder b. 1870, Hummerntrupe, Lemgo, Lippe. I need assistance in finding his siblings and details of his life from 1870 to 1898.
Any and every clue will be greatly appreciated.
Rodney Schroeder
