I found Frederick Moritz on this on-line tree: http://familytreemaker.genealogy.com/users/z/a/b/Mike-J-Zabel/GENE2-0005.htmlhttp://familytreemaker.genealogy.com/users/z/a/b/Mike-J-Zabel/GENE2-0005.html FREDERICK HEINRICH ADOLPH MORITZ: He was born June 07, 1833 Married Whilhelmina Zabel in Doelitz, Pyritz, Pommerania, Prussia Immigration: May 05, 1869, Hamburg to New York City Occupation: Cartwright (Carpenter) Died July 28, 1902 in Stella, Richardson, Nebraska.

Sadly, the immigration date doesn't match that of your 2nd great grandfather. I plan on visiting the Nebraska Historical Society Museum Library in a few weeks, though, and have added Frederick's name and date of death to my list of obituary searches. If siblings are listed, or any additional information is given (assuming I can find an obituary) I will let you know.
