I am the grandson of Henry Gordon MacKelcan, son of Douglas Walker MacKelcan. Perhaps you could provide me some details of your research. My research has Henry Gordon MacKelcan married to Helen May Armstrong on 14 October 1914. They had two sons, Gordon Armstrong born 2 March 1916 died 17 July 1923, and Douglas Walker, my father, born 17 August 1920 died 25 December 1994. I would enjoy knowing more of your research.
