Three Weddings 1970s

As the title suggests, there are three weddings in this film, ...but exactly who's?
Well the first we can say with certainty because their names can be seen on their house- Joe and Carol.
Our listing for these films notes from the film packets also list the weddings of Gail, Janet and Alison but obviously one is missing and which is which is anyone's guess but if you happen to know for sure then please do comment.
