Trademarks are used to distinguish one company's goods and/or services from those of all others. Trademark law centers on consumer confusion, confusion that can arise when companies use the same or substantially similar names as identifiers to identify the same or substantially similar goods or services.
Two companies with identical or substantially similar trademarks will not necessarily confuse consumers into thinking one company is the other, however. There are two "Dove" trademarks, for example, with one Dove marketing soap and one Dove marketing ice cream.
These Dove companies peacefully coexist because they are not in competition with each other, their goods are not in the same class, and consumers are unlikely to mistake a bar of soap for an ice cream bar.
There are numerous similar examples.
It is potentially possible for ewinn2 to continue using the trademark he is using without legal issue. It is also potentially possible that - after investing time and money into building his brand - he is sued for infringement of the senior user's registered mark.
Because trademark holders are responsible for enforcing their rights in their mark or risk losing these rights, I suspect ewinn2's use of the same name will attract the senior user's attention and a cease and desist letter will issue.
It always will be better to come up with a trademark that is unique to you alone. If you know there is another company with the same trademark you want to use, it is best to not tempt fate and to choose a different trademark.
That said, ewinn2 can consult with a trademark attorney in his area to get a compare/contrast evaluation of the real names involved, and an opinion on the risks of using the same trademark to identify his own company.
