Yes. And that is a fact about Nixon. Indeed, we can only posit that he might have had a different name because we can refer to him with the rigid designator "Nixon". How could we make sense of "The man named 'Nixon' may have had a different name"... Only by indexing it to the actual world: "The man who in the actual world is named 'Nixon' might have been given another name". That sort of index is implied by the very shared language we are using for this conversation. — Banno
...there is no apparent logical difference between the use of a name like 'Richard Milhous Nixon' to refer to someone, and the use of the DD 'The person whose name is "Richard Milhous Nixon" ' — andrewk
Nixon may have had another name. Then he would not be the person whose name is Nixon. — Banno

If people can get this, they can get Kripke. — StreetlightX
That there is no apparent logical difference between the two is shown by the fact that "Nixon might have had another name" is equivalent to 'The person whose name is 'Nixon' might have had another name". — Janus

The person named 'Nixon' might have had a different name" is about a person named 'Nixon — Banno
N&N is not much help in resolving this as Kripke fails to address accessibility relations, which determine what the ensemble of possible worlds under consideration is. — andrewk
Both are rigid if they are qualified as such and neither are rigid if not. They are logically equivalent. — Janus

Above we have the supposition that being a rigid designator is no different than having been called such by a community of language users. — creativesoul
"I don't know what you mean by 'glory,' " Alice said.
Humpty Dumpty smiled contemptuously. "Of course you don't—till I tell you. I meant 'there's a nice knock-down argument for you!' "
"But 'glory' doesn't mean 'a nice knock-down argument'," Alice objected.
"When I use a word," Humpty Dumpty said, in rather a scornful tone, "it means just what I choose it to mean—neither more nor less."
"The question is," said Alice, "whether you can make words mean so many different things."
"The question is," said Humpty Dumpty, "which is to be master—that's all."
Both refer to the man named "Nixon", necessarily so.

No. "Nixon" refers to Nixon. "The man named 'Nixon'" refers to the man with that name. — Banno
Of course, then one might say what they meant is "the individual actually named Nixon," where "actual" is to be read as some sort of indexical picking out the actual world. But then, oh dear, we have a rigid designator referring to Nixon, which was Kripke's hypothesis. — Snakes Alive
