Hi,
My maternal grandmother was Nora Margaret Baird, born 1930, younger sister of James Leslie and Geoffrey Graham Baird. She passed away in 2017. James and Geoffrey both settled and died in Kent, having grown up in the East End of London/Bexleyheath area of Kent. The family were bombed seven times during WWII, there is an article from c1942 in the Sunday Pictorial newspaper detailing the story of their harrowing experience as one of Britain's most bombed families.
Their father James Brodie Baird hailed from Glasgow and served in WWI with his twin, George, who died 28 Septemnber 1918, a day after being shot in the head in the field of battle with the Machine Gun Corps. James returned home to Glasgow and was told by his family that he should have died, not his brother, as he had goaded him into joining him in signing up underage for military service. James turned his back on Scotland and went on the road as a music hall entertainer. He met Audrey Phillis Katherine Soper at a Manchester boarding house where she was lodging while serving a millinery apprenticeship. She was granddaughter of Samuel Henry Soper, Mayor of Brighton in 1890/91. Samuel had died suddenly, leaving a fortune and the family business to his son, Samuel, Snr., Audrey's father, who gambled everything away and died bankrupt in 1909. Audrey's mother was German, of Polish descent, her family having moved to England in the 1870s.
My grandmother was not close to her brothers in adulthood, I never met them. She married my grandfather in London after WWII. He was from Liverpool, where they moved in 1954, my parents met and married and I was born in 1979. I have contact with James Leslie Baird's children in Kent and their extended families. Geoffrey and second wife Molley Gaylor adopted a daughter around 1960, I have emailed her and will get back to you with anything I find out.
I have never heard anything of a marriage to an Ethel Quin, my grandmother might have known about it, but had little desire to ever talk about her brothers' lives. I have never even seen a photograph of either of them. I will happily ask James' family if they ever knew anything of Geoffrey's earlier life and report back, but the South African stories sound unlikely to me.
Hope this helps, best regards.
