Gretchen, I was amazed to find in the 1940 census that my great aunt Blanch OATES was the governess in the Kyritz household at 24 Beacon Hill Rd, North Hemstead, Nassau. Blanch arrived in the US in July 1927, and according to the 1940 census she had been living at that same address during the 1930 census. Of course that does not help you with your family search, but if you come across any mention of Blanch I would be pleased to hear about it. Blanch was born near London, but her father came from Cornwall, while I am from Australia. Regards, Ken Oates (OPC Gunwalloe, Cornwall
