Are these actually Polish names?
Szrajba, Sreiberis, Kisiel
Szrajba and Kisiel - could be Polish indeed. The other one not.
Sreiberis,
judging from the ending, looks like Lithuanian or Latvian.
Szrajba
- the spelling is Polish.
Both seem to be coming from a German (maybe Preussian) Schreiber, just addapted to local spellings, so the family probably originated from NE Poland or neighbouring regions (Preussia had been under Polish influences for many years, the same with Inflanty/Kurlandia - so today's Latvia, and of course we had a several centuries lasting Polish - Lithuanian Commonwealth)

Sreiberis,
This is a Lithuanian surname. The 's' should have a hook over the top of it.
