There are two Kerber families recorded in the colony of Graf. Their relationship to each other, if any, needs further research.
(1) Andreas Kerber and his family are recorded on the 1798 census of Graf in Household No. Gf12.
(2) The widow and children of Franz Kerber are recorded on the 1798 census of Schäfer in Household No. Sf30 along with a note that his son Wilhelm Kerber is working in Graf.
In 1849, Konrad Herber and his family relocated from Schäfer to Friedental.
