His and her (plural)

Hello! I know that "his"is "jego"and "her" is "jej" in Polish, but how would I say "his" and "her" when talking about a plural noun, such as "rodzice?"

Thank you very much in advance!

ich -use to his her

Ich rodzice would be their parents, jej rodzice would be her parents, jego rodzice would be his parents, moi rodzice would be my parents and twoi rodzice would be your parents.
