I know very little about William Glass's siblings. After William's death his wife and children eventually permanently left Belfast because of the Troubles. His wife (Harriet) Phoebe was from the Isle of Man originally, so returned there to live with her brother Edward and her father Arthur Edward at Ballaglass Farm. I'm currently researching one of Edward's sons, another Edward, who preferred to join the RAF rather than run the family farm. He was a bomber pilot and was awarded a DFC. I wondered where the interest in flying came from - maybe he followed in the footsteps of his female cousins? I would love to know more about them. My father-in-law also joined the RAF but as a doctor, not a pilot. My husband's nephew is also a pilot with a well-known airline.
