What is the fine-grained topic of the following text: We spent the Sunday before the 4th of July at Frank's (Reggi's brother) home, his two sons John & Matt, Matt's wife Natalie & our grand Niece Parker, Connie Mae (Frank's wife) and her kids (Sherri, Michele, Garret and Steve) and their families. Only return the topic.
