Isn't anyone connected to the London Cormacks? I have a William(1782-1860) born in Stepney, London. His father was John and his mother Elizabeth. William was in business as a nurseryman with his son William John (1813-1877). My g grandfather, Cecil Bratt Cormack(1846-1916) married Mary Ann Sutherland in 1865.The names Sinclair, Crombieand Dalgetty also crop up. Family lore has it that our branch of the Cormackscame originally from Scotland.
