Samus -> Zomus : Albanian transformation?

Hello All,
Could you validate if the transformation :

Samus (sec I en) -> Zomus ( sec XII en) represents a normal
Albanian transformation. (In my opinion, yes, it represents).

"Qui cum fugeret, properans ad castrum suum iuxta fluuium
Zomus positum, milites Tuhutum audaci cursu persequentes, ducem
Geloum iuxta fluuium Copus interfecerunt."

Some additional validation - could be :
A valid Latin transformation ? (in my opinion no)
A Slavic one ? (in my opinion no)
A Germanic one ? (in my opinion no)

If we have an afirmative answer, this could indicate that an
Albanoid population (a Dacian population) survive in Transylvania
between sec I AC - sec XI AC.
