Can I get my german/bulgarian citizenship?

my grandmother (from my dad's side), grandfather, aunts and my dad is/was a german citizen and they speak german fluently but my grandmother burnt the id cards for private reasons. im sure they are a citizen in the system. i want to get my citizenship too but my dad died 12 years ago and i dont speak a word of german. do you think i can get myself a german citizenship?

and for the bulgarian citizenship, both my mom and dad's families came from bulgaria to turkey and i read online that bulgarian turks can get their citizenship. do you think that i can get one of these countries' citizenships?

learning the languages isn't a problem for me i pick up easily and im a fast learner.

Can I get my german/bulgarian citizenship?
