Fun fact, the name Santiago, is basically the same as San Diego. Originally, it comes from the hebrew Jacob (ya-akov), then Sant Iago (Iago sounds similar to ya-akob, it’s the latinization of the name IIRC). I think Diego actually comes from shortening Santiago to Thiago, and then to Diego. Basically all comes from Jacob. In Spanish, the actual translation for James would be Jaime, not Diego. I don’t know what happened there or if Jaime and Diego as somehow related etymologically.
