Which squads have been around longest?

As I browse through teams etc there are many teams with page 1 loaded with players only 20, 50 etc points. ( assumed to be newer teams with members hardly playing..)

Which are some teams that have been established a while abd they have first page or 2 with members who have stuck around clan?

Or is it pretty much a revolving door game where the same 4 guys are hopping around from team to team on several accounts lol?
