Background: If I have another son, I'd like to call him Gus. I need a formal name for Gus to derive from. Augustus is a favorite, but my husband isn't sold on it. I love Angus, but my husband, and it seems, everyone else on the planet hates it. Just Gus is not an option. My other sons are Willoughby (Will) and Finley (Finn). My great great great grandfather (mom's dad's dad's dad) was named Gustav.
Questions:
1. How would you automatically pronounce Gustav?
2. Does it sound too ethnic for an American child? (our last name is Dutch - Van Hook)
3. Do you at all like it?
4. Can you think of any alternatives?
Thank you!
