Wilke/Wilkie

Does anyone by chance have in there records a Benjiman Henry John
Wilke/Wilkie, born about 1833 and his wife Mary (Nielsen) Wilke/Wilkie, born
about 1844, somewhere in Mecklenburg. I believe they came to America about
1865/66 and settled in Clayton County, Iowa, from there they went to Greeley
County, Nebraska.
Trying to locate the village in Mecklenburg from which they orininated. Any
information will be GREATLY appreciated.

Thanks, Bob
