Usage of the definite articles with personal names

As voxanimus noted, that use is incorrect.

The only correct use I can think of that works that way is when speaking of a well-known individual.

For example, in this exchange:

Dennis Ritchie is dead.

Not the Dennis Ritchie? dmr? The guy who developed C?

That instance of the would be emphasized so that it would be pronounced just like the pronoun thee, so /ðiː/ with a long, drawn-out vowel.

No. That sentence is wrong.

Unless the Maria and Angela are works of art (or other inanimate, named objects like museums) that consume food.

If Maria and Angela are people, the would not normally be found in front of their names. It might help us understand why the website uses this example if you could provide a link to it.

Although personal names are not normally found with the definite article, there are exceptions when the name is preceded by an adjective or postmodified by a relative clause and in the case that Wudang illustrates.
