Dear German friends
I live in Brazil and I ´m doing a research about my German family.
My ancestor ,Johann Friedrich Struve ,born 1680,was "Wirklich Königl . Dänischer Major der Kavallerie und Erbherr auf Mellen".
What is the meaning of "Erbherr auf Mellen"?I know nothing about Heraldry and German nobility.
Would you explain this expression ?I thank you so much for your help.
