Note on FamilySearch profile "Our Fisher family history started in America with the arrival of John Fisher, Jr. (b. Oct 25, 1768, in Germany). His parents were John Fisher and a daughter of Valentine Himanelbarger. She died soon after the birth of her son, and John Jr. was brought to America where he was taken into the home of an uncle living in Pennsylvania. We do not know whether the uncle was of the Fisher family or the Himanelbarger. Neither do we know whether John was the only child of John Fisher Sr. and his wife of the Himanelbargers."

However, there are no known yDNA or mtDNA test-takers in his direct paternal or maternal line.
It is likely that these autosomal DNA test-takers will share DNA with John:
