How about my sentences?
A couple of problems highlighted. See how you get on.

(a) Last Sunday morning, it was sunny. Peter and his family moved into /to the house next door to Emily. They became Emily's new neighbour.

(b) Peter is a lawyer. He works in an office. Her wife is a nurse. She works in a hospital.

(c) They have two daughters. They [You're changing the meaning of "they". Be aware that this can throw the reader off course.] are studying in Emily's school. They meet and walk to school together every morning. [School-age sisters presumably live together, so it seems odd to say that they "meet" every morning.]
