you can contact your dads mom or his dad and try to have connections with them without going through your father. May Allah make it easy for you walal.
Just going to keep it 100, that’s what happened to me. I know his tribe, know the region (Biciidyahaan of majeeerteen, Werder region in Ethiopia) but I have no connection to them and have only visited my mothers clan (dhulbahante -laascaanood) and family. This is what I’ve always viewed my ‘tribe’ as. Again, I don’t want to promote any qabilism, this is just family and clan relations.
