[Callers] Dances with multiple swings- Trinity?

[Lindsey Dono via Callers]

Hi all,
I'm in the process of sorting through old dance notes, and found this: 
"Trinity? triple swing, double progression, Al Olson." If this is an existing 
dance, does anyone have the choreography?
I'm also interested in finding other dances with more than two swings, 
especially swing-to-swing transitions.I have:Back from VermontString of

Many thanks in advance!Lindsey(Tacoma, WA)
