You should be able to get some leads on on your family
by reading the baptismal records for the children of
Carl and Maria nee Thielen Roeber and Georg and Margaretha
nee Thielen Dingeldein of Christ Church, Dheinville,
Germantown, Washington Co.
You can get a little more info in the records of St. Johns,
Germantown on Mathias and Eva nee Stauss Thielen and there
will be alot on the Stauss family.
Both sets of records are available thru the LDS or Milwaukee
libraries. Both also have been transcribed, translated,
and typed so the reading is easy but watch out for
variations in spellings.
