I am am also a descendant of Mathias Klump (1 Sept 1831). My Great-Great-Grandmother is Missouri Belle Klump Wells (12 Nov 1854) of Ohio and Illinois. Missouri Belle is the Grand-daughter of Mathias Klumpp and Austeina (Ernestine) Arn. I am trying to decipher the lineage and I'm finding it difficult. The bit of information you have provided below is already infinitely helpful. Any more info or leads would be greatly appreciated.
In turn I would be happy to share what I have found, including more names of the family.
