History
The Kebo Valley Club was founded in 1888 by Charles T. How and DeGrasse Fox. In 1889 the club officially opened, with the surrounding land held a race track, tennis and croquet lawns, and a baseball field. There was no golf course built until 1892. In 1890 the club initiated an open tennis tournament, with the singles won by Valentine Gill Hall. In 1900 Henry Lane Eno donated a silver cup called the Henry Lane Eno Cup for winners of the men's singles. The tournament was staged annually until at least 1916 when it was discontinued.Finals
