One of my ggrandmothers was one of 20 children born to a couple in a tiny town. On each of the 20 birth records, her name was different. She was Reis, Rachel, Regina, Rosa, every other R name you can imagine except Rebecca, and Teresa. My ggrandmother was mostly Rachel, but she married as Regina, who was also a sister.
You can't tell what name or names is the 'proper' one. Maybe the woman had a Hebrew name and maybe not.
