Sülgren
Sülgren is a surname of Scandinavian origin. It is believed to derive from a combination of Old Norse elements. The first part, "súl," may refer to a "pillar" or "support," while "gren" could mean "branch" or "twig." Thus, the name might have originally denoted someone who lived near a prominent pillar or a distinctive branch of a tree, or it could have been a descriptive term related to a personal characteristic.
The surname is most commonly found in Sweden and Norway, though variations and related names may exist
