-ski/-ska, -scy/ski, -wicz - Polish surnames help

My Surname is "Jaskiewicz", I am completely clueless as to origins, or meaning. All I know is that its Polish, can anyone give further insight?

@Jaskiewicz
Just a guess but if it was Jaśkiewicz it might be son of Jaśko/ Jaś (John /Johnny).

Hey,

My name is Marek and my grandparents' surname was Orlenkowicz, and my great-grandfather went to New York around 1931 to live with his brother, his name was Konstantyn Orlenkowicz. If it is correct, please write an e-mail: marek.wawrzola88@gmail.com
