New Rump Immigrant discovered

Previously I have written a lot about my 3rd-great-grandparents, August Christian Wilhelm Rump and Anna Sophie Diederike Hinrich Rump, who emigrated to America about 1867-1868, arriving at New York (at least Mrs. Rump and the children), and somehow winding up in Huntsville, Alabama by 1870.  I had heard family stories about them for years before finally finding records of the family in Germany that let me extend their tree back two more generations, including finding birth records of August's siblings and cousins from German church records.

Using Ancestry DNA, I found a couple of Americans with Rump ancestry who had a common DNA match with me, but they were not from the Rump line who came to Alabama.  Looking at their Ancestry trees, they trace back to an immigrant to New Jersey, Charles Rump (1871-1951).  One person, who lists the New Jersey death certificate as his source, has a birthdate for Charles of 27 July 1871, which exactly matches the German church birth records for August's cousin Carl Friedrich Rump.  Furthermore, he lists the nickname "Carl".  Not only that, he lists the parents names as Friedrich Rump and Amelia Neckrog.  From the German records, that matches (except for spelling) Friedrich Hermann Rump and Louise Frederike Amelie Nicking.  I don't believe the person who entered this (I am waiting to hear from him.) was using the German records for this information because the spelling differs and he cites the death certificate.  So we have a multiple DNA match (from New Jersey, where I don't have any known relatives for many generations), a birthdate match, and a close name match for Charles/Carl and his parents from the US records and the German records.

So, I am pretty confident that August's cousin Carl Friedrich emigrated to America like his cousin around 1885, about 17 years later.  August became the head of a large family in Alabama and Charles in New Jersey.  I wonder if he Charles knew about August.  Interestingly, Charles' occupation on the census is variously listed as dock laborer, freight barge, and boat man (coal company).  August had been a sailor and a ship's carpenter, and their was another Rump on some of the crews with him when he was with the North German Lloyd (Norddeutscher Lloyd) shipping company.  So it seems the Rumps had an affinity for sailing.
