I appreciate your attempt to contribute, but you shouldn't state possibilities as facts.

You can see 5 dummies in the game, and there may be even more in the Underground. There is no way to know who was the cousin Mettaton wrote about, and there is no reason to assume that all the dummies are his cousins. What we do know is that Mettaton and Napstablook are cousins, and they have another cousin who left to become a dummy. We also know Dummy and Mad Dummy are cousins (while Mad Dummy and Napstablook appear to not know each other). And there are at least 3 more dummies in New Home. That's all the game shows. Anything else is just speculation.
