There are two Grossmann families from Warenburg. Their relationship to each other, if any, needs further research.
(1) Johann Christoph Grossmann and his family are recorded on the 1798 census of Warenburg in Household No. Wr093.
(2) In 1790, widower Johann Peter Grossmann moved from Warenburg to Lauwe. Peter Grossmann from Warenburg and his family are recorded on the 1798 census of Lauwe in Household No. Lw26.
