It goes by generation.
When a child is named after the grandfather, rather than the father (in which case it would be "junior," instead of "II").
you should probably use the roman numerals. that is corect
the apple II was the 1st computer to use a mouse so I'll say that.
Commonly, if you have a parent whose name is the same as yours, the father's name may be senior, yours may be junior, and your child would be The II. If your mother has the same name, her name would be based off the grandparent's name (Jr if the grandparent's name is a senior), and so on. The II is normally used after the family has been named Senior and Junior of a same family member's name. I could be wrong though, because a junior can be named The II too.
