You should contact the nearest Swiss embassy/consulate to you and see what they say.
There is family reunification in place - it would be similar to this I think. https://www.ch.ch/en/family-reunification-eu-efta

If you're over 22 then I doubt you have any possibility if your parents didn't register your birth abroad when you were born. Here is the criteria for simplified naturalisation. https://www.bfm.admin.ch/bfm/en/home...uergerung.html
Otherwise, sorry, but family or no, if you can't get an employer to sponsor you for a permit then you can't get one. As a non-EU national the only way to get a permit is to get a job here or to be so independently wealthy that you don't need to work. For any employer to be able to hire you, they have to show they can't find a Swiss/EU national who could do the job. https://www.bfm.admin.ch/bfm/en/home...zulassung.html
