My understanding is the Jr/Sr name appendage can happen in a few instances:
1) A person is named something like "Roy G. Mercer", and then names his son the same thing. Informally, it is ok if people call the dad "Sr." and the soen "Jr".
2) A person is named "Roy G. Mercer Sr.", and has a son who he names "Roy G. Mercer Jr." In this case the Jr. is not implicit but explicit.
3) Any combination of 1 and 2.
Also, same question for "Roy G. Mercer I" for the dad, and "Roy G. Mercer II" for the son. I'm fairly certain though that the I and II disgnations must always be expliit and never implied. Yes???
