I am looking for my Dutch ancestors. Mr great-grandfather was Simeon(Simon)Danhoff who emigrated to the USA from Groeningen sometime between 1875 and 1880. He was born in 1850. His father was Herman Danhoff. Simeon married Tantje Popping (or Papping)date unknown. Her parents were: Father-Hendrickus Popping(Papping) and Mother-? Vegter. A daughter, Frances Danhoff may have been born in the Netherlands in 1875.
