It would be quite a trick to have 4 Hellcats fly over your house. There are only 5 airworthy in the world and one of them is in the UK. Two are in California and the other two in Texas. Avengers are pretty common because they were used for fire bombers.
Corsairs sound like Hellcats (same engine), and there are a lot of them flyable.
The thing to check is if there are any air shows in your area, or if there is an air show this weekend in the direction they were flying.

Possibly F8F Bearcats?
Seemed to be a pair of Bearcats that flew over Grand Forks few times for several weeks a couple of years back. I never really got close up look. At first I thought they were Hellcats. At a distance they did appear to be Bearcats.
Used to get the US Forest Service TBF's (five of them) fly over. Going between Minnesota and Montana.
In the flood of 1997, a US Forest Service A-26 dropped fire retardant on the downtown fires.
Bearcats are quite possible. There are a fair number of those still around.
The Bearcat had the same engine as the Corsair and the Hellcat, but was a much smaller airplane. At a distance it has the same squared off features of a Hellcat so I guess it could be mistaken for one.
