Serious question can it only be senior and junior in America then if all initials are the same?
We do not really use the term in England but if we did the fact the first name was the same would be enough.
Depends on what part of the country that one is from. In the south the son could be refered to as jr. even if only their last name is the same.
But, then again they could just be called bubba.
All journalists should be aware of this, but alas, that's asking a lot from this group. I truly think they do it on purpose.
