Is Steigelman a German last name because I have been looking on the internet and nothing comes up about it being German?

You're right, "Steigelman" doesn't appear to be a common German last name. There are a few possibilities:

* Misspelling: It's possible the name you're looking for is a slight variation. Maybe it's "Steigmann," "Steigelmanis," or something similar.

* Rare Name: While not common, it could be a very rare German surname that hasn't been widely documented online.

* Non-German Origin: The name could have origins in another language or region.

To investigate further, you could try:

* Searching for variations: Try different spellings of the name in your online searches.

* Using genealogical databases: Websites like Ancestry.com or FamilySearch may have records related to the name, even if it's rare.

* Consulting with a genealogist: A professional genealogist may be able to help trace the name's origins and provide more information.
