Georg Fredrik Arentz von Krogh

Wrong placed person?

    A famous Norwegian general in the army's cavalry division, he was suffering a little too much social persecution as a Jew and as a Protestant, so he rebaptized himself and his wife as Boelemans to fit in with the Dutch/German community there.  He changed the name on September 8th and 9th of 1743, rebaptizing and changing the names of his children on the 15th and 16th of that month.  

His skills as a military officer were legendary and he corresponded frequently with the Kings of Norway on military matters right up to his death. He moved the family to the Netherlands shortly before his death.
