洛琳 is most often the dub name for 'Lorraine' - notably Lorraine Baines, Marty McFly's mother in 《回到未来》 (Back to the Future). It also serves for 'Lauren' in some translations. The slightly different 罗琳 (Luólín) is reserved for J.K. Rowling.

洛 (luò) handles 'Lor-/Lau-' and 琳 (lín) is a bright-jade character favored for feminine names - Chinese transliterators routinely pick it for foreign names ending in '-ren', '-rine', or '-ryn' to make them feel like a girl's name.
