Miguel and Camila are first cousins because their respective parents, Isabella and Jose, are siblings. Since Miguel is the son of Isabella and Camila is the daughter of Jose, they share a set of grandparents (the parents of Maria, Jose, Carlos, and Isabella), which establishes their relationship as first cousins. Carlos, being one of Maria's brothers, is Ana's uncle. Ana is the daughter of Maria, making all of Maria's siblings, including Carlos, her aunts and uncles. Therefore, Carlos is Ana's uncle.
Maria has three siblings: two brothers, Jose and Carlos, and one sister, Isabella. Maria's daughter, Ana, often plays with her cousin Camila, who is Jose's daughter. Isabella is married to Eduardo, and they have a son named Miguel. What is the relationship between Miguel and Camila, and how is Carlos related to Ana? Provide a very brief response.
