One counter-example for "People have, at this point in time, one full name which they go by." I learned from the 2020 election concerned the Georgia voter fraud claim that someone used the name "James Blalock" to vote, years after he died in January 2006.
Thing is, it was his 96-year-old widow, "Mrs. James Blalock Jr.", who voted. That was the name she registered as, back when using "Mrs. <Husband>" was a common custom.
