I am related to descendants of this family and have some information on their origins in Prussia. These Wendts and Hoefts attended Trinity Ev. Church, Brookfield, now Trinity United Church of Christ, Capitol Drive and Calhoun Road. The records for this church have been filmed by the LDS and are available through Family History Libraries.
Other members of this family attended Friedens Church in Milwaukee, also, I believe. These records are also available through the LDS.
