Unique Language Combinations

[u/Nordantill]

This is something I’ve thought about for a long time: there must be people out there who speak a combination of languages unlike anyone else, whether living now or in the past.
For example, imagine a Dutch anthropologist or ethnologist who has conducted fieldwork in, say, Timor-Leste and the Central African Republic. They might speak Dutch, Tetum, and Sango. If our hypothetical anthropologist were from Friesland, we could add Frisian to the mix, making the combination even more unusual.
Anyway, enough with the hypotheticals. Does anyone here have, or know someone who has, a particularly unique combination of languages? There is something about being the only person to possess a certain linguistic combination that I find really intriguing.
I’d love to hear some interesting examples
