Heinrich Hilsmann S Arrival

I finally solved the mystery of my great-great grandfather Hilsmann's arrival to the U.S. I have his discharge document from the Hanoverian Army dated June 30, 1853 and a transcript of his parish record that he had made before leaving Germany. I have the deed to the family cemetery plot purchased 1860. I though I'd found him on a June 28, 1858 passenger list for the steamer Repbulik from Bremen. The first name was abbreviated Hch, which is a common abbreviation for Heinrich. Howevere, the age didn't match, but the place of origin and occupation matched, so I chalked it up to a recording error. Later I found his declaration of intent to become a U.S. Citizen dated November 15, 1854. This was too much of a discrepancy to overlook, so back to 7,the passenger lists. I finally found him and a younger relative, Friedr., arriving on the steamer Hansa from Bremen on August 1854.
