Looking for information on COOK hallmark

I have 2 pendants silver with turquoise with the hallmark COOK on the back. I have searched all over the Internet but don’t have a clue to the silversmith or origin. Any thoughts??


The bails on these pendants are purchased from a supply store, meaning that this is most likely a novice silversmith. Cook is a Navajo last name but I am not familiar with this artist or hallmark. Thank you for sharing.
