Looking for Grandma's (Paryka Solohub) sister in Western Canada?

Paryka was married in Canada to Nicholas Barron. They lived in Port Robinson, Ontario. Children named Paul, Peter, Adam, Ann, Philca, and Phillip. They came from a village in Ukraine called Vitcu ? It might be in Poland after WW11. I want to get in touch with her sister;s children if possible. Thank You.
