Gemza-Ramik Family Details

I want to document a few details here because I'm confident they are correct but I don't have source documents for them yet. Last fall Aunt Ann spoke to her older sister, Aunt Cecele, and Cecele provided new information about their father's family. This is from an email from Ann's daughter Suzanne to me:

My mom spoke to Aunt Cecele.  All she could remember was that Walter Gemza's mother was named Ava Gemza but it is spelled Ewa in Polish.  Walter Gemza is Stepahn Ramil's first cousin.  Stephan's mother and Walter's father were sister and brother.  She remembered the sister - in- law's name because she was the one around and Walter's father was dead.  Stanley Gemza was Walter's younger brother.  The reason I am mentioning him is because he and his wife, Anna, lived in my mother and father's neighborhood in Trumbull.

I've tried to capture this information in my Ancestry tree:
