We’ve already met the Warren family on this blog. John was the younger brother of Lilium Lancifolium Warren, infact, she was named as a witness at his wedding in 1915 and when he died in 1930 she was awarded probate of his will.
John was born on September 27, 1886, the son of Alfred Warren, a goods guard, and his wife Marcellina.
His employment records with the GWR reveal he began work on May 5, 1902 and as his obituary states ‘he had been in the Company’s service for 28 years, the whole of which time he had spent in the accounts section.’
He married Frances Alice Iles at St. Paul’s Church, Swindon on April 12, 1915 and served in WWI. Unfortunately his military records are incomplete and all that survive indicate that he served as an Acting Sergeant in the Royal Army Medical Corps and that he was discharged on July 11, 1919.
His many friends will learn with regret of the death of Mr. J.O. Warren, of the Chief Mechanical Engineer’s Department, accounts section, Swindon, who died on January 20, after a short illness. Mr. Warren was 43 years of age and had been in the Company’s service for 28 years, the whole of which time he had spent in the accounts section. He leaves a widow and one little girl, and his loss is greatly deplored by his colleagues, many of whom attended the funeral on January 24.
