This is a long shot! I have reason to believe that my great uncle came to be called Irving Kaye. He probably started off life as Isadore Kalusky or possibly Ellis Kalusky and he was probably born in Kimberley in South Africa in about 1901. Sometime by the middle of the twentieth centuary he had moved to the United Kingdom. He may have been a musician or at least have been musically inclined. His parents orginated from Eastern Europe - Kshinev and Berdichev but went to South Africa via a time in London. Irving Kaye would have had at least 2 brothers and a sister.
If any of this sounds familiar let me know and we can see what other details might match.
