Nice list for Bermuda.
Are you sure the surface of Bermuda was a cement-like hard court?
My reasoning is twofold:
1. British sources used "hard" for surfaces that today would be called clay. As a British colony it would be natural to use this in the case of Bermuda.
2. I have some copies of American Lawn Tennis where the event is described. I'm pretty sure it's clay.
Here is an ebay pic from 1934
1950 Elizabeth Rosenquest d. Helen Rihbany 5-7, 6-3, 6-4
1951 Beverley Baker d. Barbara Scofield 9-7, 7-5
Rosenquest (later Pratt) always went by "Betty"
should be Beverly and not Beverley (I add the extra "e" this a lot myself!)
I will double check my ALT's to confirm the surface and try to pick up results for 1942-43 and 1945-46.
