Genealogy / Family History: Podsiedlik? My great grandmother had parents from Poland [4]

I am trying to piece together my odd family history. To be honest, I'm not very good at this sort of thing, although I'm very interested in it. Anyways, my great grandmother's last name is Podsiedlik. According to her, her parents were from Poland, and she and her siblings were born shortly after they arrived. I love her to death, but her memory isn't as well as it used to be, so she doesn't remember much of the Polish language she once new. Also, she doesn't seem to like to talk about her parent's and such very much. All I know so far is both her parents names and all their kid's names. I used a few genealogy search sites and such, but got very little results for the name Podsiedlik.

So, right now I really would like to find out about the name Podsiedlik. I can't figure out what it means, even though I have tried. Also, I can't figure out if it is an uncommon name or if there is another reason my searches never return many results.

My 1st post! :D
