i'm confused so...

are miguel caldera and maria cid siblings or is miguel caldera her uncle. miguel's will refers to maria cid as his sister, but tomas villegas's ordenes refers to miguel as being maria cid's uncle.

here's the link to the page on tomas villegas's ordenes that states miguel is maria cid' uncle.
