no, not related. Friedrich Gotthold Struve was a member of
a family of reputed scholars, and I think he died in
Oldenburg in Holstein, not in Niedersachsen.
My family (backwards) shows farmers and a day laborer.
Mind : I did not say "only". Hard-working people on dry soil.
With greetings from your roots,
Klaus (Struve), in Kiel (but not born here in Kiel)
