As I'm the only one with the name Margit Wimmer on FAA it is not a problem but maybe could be with google search.
I need a name for a zazzle shop, wanted to have my name but was not possible. When I typed in my name in google (also looked at images) there are a few people called Margit Wimmer, saw two others who are also artists, one of those represented in a gallery... So - I was thinking about a pseudonym, however, there might be cons.., using real name and pseudonym in text maybe, but still afraid it would be more confusing and would not be so good with google search for me then..
