Genealogy / Slominski coat of arms [3]

Good day, my brother and I are interested in our family name and coat of arms. Since I can remember I've always been interested in the Scottish clans/ Irish clans and festivals (we don't have Polish ones near me) Scottish games etc. Come to find out our Polish heritage that Poland had clans. So amazed.

Any info on finding my family history would be helpful.
Surname. Slominski
Thank you.
