Ceylin del Carmen Alvarado won the Elite Women's Cyclocross World Championship in February 2020. She's Dutch, but was born in the Dominican Republic; so her names sounds quite different from what you normally encounter in European cyclocross.
Did you arrive at this page because you're wondering how to properly pronounce "Ceylin del Carmen Alvarado" - especially the "Ceylin" part? It's correctly pronounced "Say-Linn". In various TV and live stream broadcasts, I've heard "Kay-Linn" and also "Celine" (as in singer Celine Dion) which appear to both be incorrect.
According to wikipedia, the paternal family name is "del Carmen", while the "Alvarado" is the maternal portion.
In this interview found on Shimano's Youtube channel, Alvarado is asked to introduce herself on camera, in English, and pronounces her own name "Say-Linn". Click to listen: https://www.youtube.com/watch?v=EuL6KNYhXO4
