William was one of a large family of five boys and five girls belonging to Andrew McIlhagga who was born about 1880 in the Ballymena area and Elizabeth Todd who was born in Gracehill about 1883. Elizabeth may have been part of the Moravian community which made its home in that central Antrim village. I am unsure who Andrew's parents were. Married at Ahoghill Church of Ireland in 1906 Andrew gave his father's name as John McIlhagga of Queen Street, Ballymena.
If anyone knows more about the history of this family I would be delighted to be in touch, particularly if the information contained a suggestion about who might like to have the above Salvation Army badge. It is a small heirloom that should go to someone who perhaps remembers Dorothy McIlhagga.
