The New York Times reports that the 1922 Bermuda Chmps were played on a cement court painted green.
A new stadium was built and used for the 1932 event. The surface was en tout-cas (clay).
I have found the name of the first champion. She was Mrs Eugenius "Eugene" Harvey (nee Bessie Gosling).
There was a Chmps in 1915. The last day was March 12. Held at the Hamilton Hotel Tennis Club.The NYT doen't mention a women's singles winner. The doubles was won for the third year running by Alice Gosling and Bessie Harvey.

* This player was Ruth Riese; her maiden name might have been Wise.
Yes and not.
She was Ruth Riese, of Saginaw, Michigan.
But her maiden name was not Wise, because in the draw of 1920 U.S.Clay Court Champs. there were Ruth Riese and Ruth Wise (and also another Ruth, King). 1920 results
