Thomas is Charlotte's only brother, and their mother, Evelyn, has one sibling, a brother named Paul. Paul is married to Linda and they have three children: Sarah, George, and Rita. How are Sarah, George, and Rita related to Thomas and Charlotte? And is Linda in any way related to Evelyn? Provide a very brief response.
Sarah, George, and Rita are the children of Paul, who is Evelyn's brother. This makes them the cousins of Thomas and Charlotte, since their father (Evelyn's brother) is the sibling of Charlotte and Thomas's mother. In family relationships, the children of one's aunt or uncle are called cousins.

Linda is married to Paul, making her the aunt by marriage to Thomas and Charlotte. While Linda is not biologically related to Evelyn, she is Evelyn's sister-in-law because she is married to Evelyn's brother.
