Searycz or Sayrich
There is a British surname Surridge. Not especially linked to Scotland as far as I know, however not all Scottish people have Scottish surnames; some have English or Welsh names. As far as I know, Surridge means someone who came from the south.
As the person above mentioned, there were certainly Scottish mercenaries in Poland and some have left their surnames there until today. Not all were from highland clans though, most were in fact from the lowlands closer to the English border.
