Sofia is Javier's daughter and Carlos is Javier's brother, making Carlos Sofia's uncle. Therefore, Sofia and Carlos's son, Andres, are first cousins. Maria is married to Carlos, so she is Javier's sister-in-law, and since Pablo is Javier's son, Maria would be Pablo's aunt by marriage. This relationship may make her an important person in Pablo's life because she is a part of his extended family through her marriage to his paternal uncle.

How are Sofia and Andres related to each other, and why might Maria be considered an important person in Pablo's life? Make your response very short.
