He was the son of Johan Georg Euler and Anna Catherine Pobb. This family had several children who settled in Woodsboro, Fredrick County, Maryland. Johan Jacob's brothers also settled here as well.
I can send you my geneology report that covers this family and you are welcome to browse it for potential leads. It is so large I can send you 3-4 generations to make it easier.
