Yassavran has /tsúvri/ "hammered dulcimer" > modern Yasaro /sûuri/, so that would work for "Yassavran" if it was actually "Yatsavran". Hmm, would that work for "Simikal" (< *Tsimikal)? Maybe so. It doesn't seem entirely implausible that initial /ts/ would change to /s/ in both languages. As it is, it seems modern Yasaro has more words beginning with /s/ than with /h/, so it seems strange if all of those were /ts/ in Yassavran, but maybe some could be /ks/, /ps/, /st/, or some other clusters.
