answer:Yes, a Sr becomes a Sr only after a Jr is born. I would say that it is just an ego boost, but people can name their kids whatever they want. I think it’s important to let your kid have his own identity – he’s not solely an extension of the father. As for women, the idea of “carrying on the family name” doesn’t apply because women usually take their husband’s last name. If a female gives her married name to her daughter, that name will probably change when that girl is married, meaning she would no longer be a Jr. Men pass on the family name; women do not.
