Sorry for the delay. Interested in a William Irwin who was married to Sarah Lewis Knox in Whitehead on 1 Sept 1919 by Rev David Brown Knox, Presbyterian Minister at Whitehead. She was born in Belfast and William Irwin and she were neighbours in Thorndale Avenue (Nos 22 and 28) in 1911 census. He was booking clerk and probably posted to Whitehead by railway company. Her address at marriage also Whitehead and I wonder if D B Knox was an uncle. Her father Joseph Knox born Co Antrim ca 1853. Does anyone have more information about this family? (John Armoy Knox was a brother of D B Knox.)

Many thanks
