I would say delete the anonymous ones, the Wikipedia articles aren't even a good source–they're just transliterated from the Chinese transliterations of these names. I also can't find any sources for these names besides the Wikipedia articles and the sites that link to them, and besides Si-mung, that is all I get in a verbatim search as well. Lastly, Pi-de-ta-di’ is straight up an error–it is not just
Peter, it is a transliteration of Chinese 彼得大帝 which means "
Peter the Great".
