My 4ggrandfather, George Brock, lived in Nodaway Township, Buchanan County, Missouri from around 1838 until his death sometime around 1850. I am trying to locate any cemeteries which may hold graves from that era in what was then Nodaway Township. Any suggestions, please?

Also, anyone with information about the children, siblings or wife of George Brock is most welcome to reply. He is one of those mysteries in our family tree. His wife was named Nancy and the only child we know of is John William Brock who married Rosetta Pearson in Buchanan County, MO in 1847.
