Question:

Does anyone know the meaning of the name......?

does anyone know the meaning of the last name Deusterman(german) and the last name Melstrom?

Thank you so much for your help...

Best Answer - Chosen by Asker: Deuster is...German: nickname for a grim or low-spirited person, from Middle High German dinster, duster ??black??, ??dark??, ??grim??.

So I would guess the man on the end is redundant and probably added to Deuster some time is history. I also saw that Deusterman from the Census originated from Minnesota in the U.S. in the ~1880's.

Melstrom but may be a short form of Maelstrom which means:
a large, swirling body of water.
