in what sense?
Historically, Stare Tarnowice used to have its own USC (however, the USC moved around quite a lot – Repty Stare, Opatowice, Lasowice…). Tarnowskie Góry, of course, had its own USC. I have indexed the marriages of Stare Tarnowice USC 1874-1905 here: http://www.geneteka.genealodzy.pl/index.php?rid=5787&w=12sl&op=gt
In the modern sense, only the USC Tarnowskie Góry remains. It’s also where the records from ~1905 till 1945 of the former USC Stare Tarnowice are stored.
