Many people in America know of the famous Schick razor blades. Many Russian Jews know of the surname Rinsky. This surname seems to be a combination of the two. My paternal great grandmother's maiden name is Schickerinsky. She is Anna Schickerinsky. I am still not certain of her father's name but the only piece of information I have at this time states that his name is Waldemar. This information came from FamilySearch.org. Indexing Project (Batch) Number M00943-4 System Origin: New_York-ODM. Source Film Number 1558696. Which is the Manhattan, NY marriage record for Annie or Anna as we called her, and John Christ.
