Kate was fathered by Vilhelm Frimann Marcher. Though I don't speak Danish, I know enough German to guess that "Frimann" is a cognate of the German word "Freiherr," meaning Baron.
No, German
Freiherr is in Danish
friherre, meaning "free lord". Frimann is just a bourgeois surname meaning "free man". The most famous Frimann was Norwegian priest and poet Claus Frimann (1746–1829). Interestingly Vilhelm's grandfather was a priest and born in Bergen, Norway in 1748, so perhaps he was named in honour of his grandfather's famous friend/collegue/compatriot.
I too have always been curious about Vilhelm Frimann Marcher's background. I was thus very happy when I found this Danish genealogical link with all his known ancestors:
Vilhelm Frimann MarcherTurns out that he had a lot of siblings and that Frimann just was a middle name with no direct ancestral ties. His parents were Christine Petersen and Eiler Christian Hansen Marcher. His mother's family seems to be rather unknown and his father's family just bourgeois. In the 17th century, when Scania became Swedish, they moved from Malmö to the island of Bornholm and assumed the name Marcher. His grandfather was a priest and his father a large-scale farmer I guess, since he leased (from the Counts Scheel) Trudsholm manor on Zealand, where Vilhelm was born. So he was "to the manor born", but as a bourgeois to a leased manor....
However, his father Eiler Christian and great grandfather Eiler Holch Hansen Marcher both seem to have been named in honour of the family's noble link: Vilhelm's great great grandmother Elisabeth Sophie Eilersdatter Holch or Holck (1693-1774). She was born as daughter of Baron Eiler Holck, at the magnificent castle of
Holckenhavn. on Fyn, which Christian V gave his Governor of Kronborg (probably as compensation for lost estates in Scania) after it was confiscated from Christian IV's treacherous daughter and son-in-law Leonora Christine and Corfitz Ulfeldt. Through the Holck link the Marcher family descends from many ancient Scandinavian noble families, possibly also from royalty.
BTW Elisabeth Holck's mother Baroness Ingeborg Holck née Vind was divorced from her husband and exiled to the Marcher's ancestral home Bornholm for "frivolity"! Her maternal grandfather was the famous Admiral Ove Gjedde. And her brother Frederik Vind was an ancestor of the Danish magnates the Counts Krag-Juel-
Vind-Frijs. Here is a wonderful illustrated genealogy of the Barons Holck with interactive links to other families:
