What’s True
Vance was indeed given the name James Donald Bowman at birth, after his biological father …
What’s False
… but, officially, he has only changed his name twice, not three times. The first name change was the result of his adoption by his stepfather. The second name change was one he requested as he was about to graduate from Yale Law School, a year before he got married.
He changed what he is publicly known as at least 3 times, only 2 were officially recorded. Seems like it is important to him to be referred to by his chosen name, nothing wrong with that.
