Bill and Kyle:
Yes, the Kerwin and Lynnewood Hall are old club invitational tournaments in the better ball of partners stroke play format. I don't know how old the Kerwin Cup is but I know the Lynnewood Hall is really old even though it was discontinued for a number of years and then restarted not that long ago.
There are a lot of great class A amateur tournaments around some of which have been going for a long time. They come in different formats from individual stroke play to better ball stroke play to individual and team match play. They are invitationals whose criteria includes earning invitations for competitive merit in other tournaments to straight invitationals.
Some of the most notable are The Anderson Memorial at Winged Foot, The Travis at GCGC, NGLA's National Singles Tournament, Seminole's Coleman, Pine Valley's Crump Cup and Merion's Hugh Wilson (that has been discontinued), the Sunnehanna and the Northeast Amateur. I think the last two count towards national ranking points.
The Baily Cup and Lesley Cup are a bit different as they are interclub or interstate competitions and cups. Then there are merit competitions between associations and regions like the Compher Cup (New Jersey State Golf Association against the Golf Association of Philadelphia (GAP) and the Mason Dixon Matches (The Mid-Atlantic Association against GAP).
Dan, I'm glad to see French Creek and Applebrook now have the Hanse Cup. The competitors sure don't have far to travel between those two clubs.
The top flight ladies have much of the same. The Griscom Cup just may be about the oldest continuous inter-state, inter-association annual competition in America. It is named for Frances Griscom of Merion who won the US Amateur in 1900. She was the daughter of Clement Griscom, the man who owned the original nine of Merion Cricket Club and the sister of Wilson Committee member, Rodman Griscom, who became Merion GC's first president when it took the vote to split with the Merion Cricket Club on that day that shall live in infamy----December 7, 1941.

That's right----all the "jackets" you saw yesterday late afternoon as you drove up Golf House Rd were the Baily Cuppers of Merion, PV, HV and GMGC. Too bad you didn't run into those clubs' head professionals Nye, Clark, Connelly and Gilbert duking it out in a fist and knuckles match over on the West Course yesterday afternoon. They were all of the same opinion that Merion West may be the most interesting little golf course of under 6,000 yards there is. You should have stopped in; I would've bought you a drink or two, particularly seeing as I was breaking some rules anyway by smoking in the wrong place for which I was very politely flagged!
What are some others out there like these around the country or around the world?
