The catholic cemetery in Spring Garden Township is St. Patrick's / St. Mary's cemetery. It is one cemetery that has been shared by the two separate parishes that are in the city of York about one block apart from each other. Currently, the cemetery is not listed on the Diocese of Harrisburg website as one of its cemeteries that it maintains. I think each parish keeps its own burial records on its own parishoners who are buried there. If you are familiar with York, it is located on Starcross Road, which runs off of South George Street about 1/2 mile from York Hospital. The area is also known Violet Hill.
