I may be of some help or vice versa. Nicholas Bowe (b. 1841) was my GGGGrandfather and had many descendants. Nicholas #1 (b. 1823) also had many descendants. Nick #2, who I think is the one born 1847, didn't have many children and appeared to have married twice, once to a Frincisca and once to Mary and appears to have died after 1920. There's also a Jacob Bowe born in 1850 who could be the brother to any one of the Nicks. My biggest question is whether they're all related, either cousins or brothers. It's not a particularly common name in Germany and it would be quite a coincidence for them to settle in the same town.
