Hello all,
Thank you for all the responses, ideas, and questions. Here's what else I can tell you in response to those questions posed--tried to keep it brief:
Our Dad Alexander Reid McKay was born 07/02/1923, three years before the marriage of our grandfather, Robert Cochrane Harvey and Margaret Harvey, (04/05/1926)--that was an irregular" marriage--she was shown as Spinster--so not married previously to someone who might have been Alexander's Dad as someone speculated. They gave birth to their son James when they were living at 52 Main St, Thornliebank on 10/11/26 and son Richard 11/06/1930--same address. By then Robert was managing Alhambra Theatre in Perth and living in the White Horse Hotel there. It appears that sometime in the early 1930s our Dad, Alexander, came to live with them. Our Uncle James told a friend that our Dad was dropped off by a strange lady at their house when James and Richard were young--not yet in school--that is how we've come to suspect our Dad was seven or eight at the time he came to live with them.
In 1934 Robert was appointed Manager of Kings Theatre in Dundee and the family were living there by then as my Uncles attended Craigie Primary school and Morgan Academy (from 1934-1937). There was no record of our Dad Alexander attending either of those schools. We know the family was in Inverness at some point as well as our Grandfather Robert was later appointed northern Supervisor for Caledonian Associated Cinemas. We wonder if maybe our Dad, Alexander, may have stayed in Glasgow with Aunt Lizzy (Elizabeth Burke) as he commented that he used to wait after school in the tearoom where she worked (she was a cook not a waitress as I earlier suggested), and then would walk home with her.
In 1945 we know Aunt Elizabeth Burke and Uncle Willy Burke both lived at 22 Summerlea Road, Thirnliebank--they were brother and sister and neither ever married.
One other question posed was where the name Kaye Burke Harvey came from--I asked our Dad that when I was little and he told me that his mother gave him that name because she liked it--we now assume it came from McKay. And Burke was her maiden name. Kaye was pronounced Kye.
Hope this additional detail helps. And thanks again for all your suggestions and questions. So very much appreciated.
I can supply additional information on the Burkes and Harvey's if it would be helpful. Our grandfather had four brothers, not three as I said earlier. And Margaret had an older brother, Thomas, as well as Elizabeth and William.
