Re: What was Ginsburg & Klausner, S Fallsburg, NY (Catskills) not listed as hotel #usa
Have you checked the website for the Catskill Institute? This is an organization "to promote research and education on the significance of the Catskills on Jewish Life" It was founded in 1995 at Brown University.
The website is replete with information, including extensive lists of hotels and bungalow colonies.
Under Loch Sheldrake, there is listed only "Millers" Bungalow Colony. It is possible that there is more archival information available from the Institute. I recommend exploring the web site for anyone interested in information connected with the Catskills.
