Hello Oren,
The glacier Gammel Hellerup was named by Svend Sølver during the Mørkefjord expedition in 1938-39, Gammel Hellerup was the high school he went to, I actually told the story to the rector of the school today, a few years ago, and he was not aware of a glacier named Gammel Hellerup?
Almost the same story I could tell about Zachariae Istrøm, I met Bobby Zachariae (a well known researcher here in Denmark) once and told him about a very impressive glacier that was named with his family name and not only that but after his grand grand something Georg Hugh Robert Zachariae, he thought I was joking, but luckily he had a smartphone and googled it instantly and thanked me a lot for the information.
