Marja Grólmusec (German: Maria Karoline Elisabeth Grollmuß), born 1896, was a Sorbian publicist and a member of the resistance against the Nazi regime.
I absolutely love this name and am glad it means berry in Finnish, as I was always annoyed to be told it was another form of Maria, which I do not like much.
