I am researching several of the families of Cole Camp, MO.Some of the BECKMANN's moved to Miami Co, Kansas.They formed the Trintiy Lutheran Church, but it split over the argument about raising a new church building.Part of the group then formed the Highland German Episcopal Church nearby.
The oldest BECKMANN family I have is: Johann Heinrich BECKMANN (1809-1887) and his wife, Rebekka (?-1873).Their children: Freidrich (1835-1872); Heinrich Wilhelm (no dates); Rebekka (1843-1916) and Katherina Margarethe (?-1875).Entire family born in Hanover, except the last girl, Katy, who was born in Missouri (probably Benton County).
Rebekka married Dedrick MUELLER; Katherine married Martin GERKEN and Freidrich married Katherina GROTHER.
I have census records, marriage records, burial records, etc. to share, if you are interested.
