Genealogy / THE MEANING AND RESEARCH OF MY POLISH LAST NAME, SURNAME? [4500]

My surname is Żeglicki

I'd love to know where it came from - all I know is that my grandfather was born in Rzeszów in 1920 and there may be some family in that area still, but don't know if his ancestors were from that area as I believe his father (my great grandfather) was in the Polish Army and may have moved around. I know at the outbreak of WW2 my grandfather lived in Wilno (now Vilnius, Lithuania)
