◆ HIB Menologies SJ :
He was a Missioner in Australia. It is likely that he was a Missioner up country near Burrows, but later on was Administrator at St Benedict’s in Sydney for many years. It is unclear where he studied Philosophy and Theology, or was Ordained, but it is likely to have been New South Wales while it was still a Crown Colony, and before it got a Parliament and Government of its own, as he was one of the few Priests who were pensioned by the retiring Imperial Government. He had an income of £250 a year up to the end of his life.

In 1887 he was admitted to the Society and was the oldest Novice. He made his Novitiate at the North Shore Residence, and remained there until his death 25 January 1900. He was a very edifying old man, full of zeal for instructing the people. He died as he had lived, in a holy and edifying manner, and he was buried in the Garis Hill Cemetery, near the Novitiate in Sydney.
He often preached at great length, and as he spoke rather fast, he was hard to understand. However, he was esteemed by all as a holy man. In the North Shore Residence, he was charged with the duty of ringing the bells for various duties, and remarkable for his punctuality.

Edward O'Brien was ordained to the secular priesthood, and was an early missioner in Australia. He arrived at Sydney from Carlow, 10 July 1852, and was sent by the archbishop Dr Polding, as the first resident priest of Braidwood, which had a resident population of about 212. He built the first parish school, which was opened, 29 January 1859, followed by St Bede's church, 1862. He also built churches at Reidsdale and Krawarree and rebuilt the church at Major's Creek which had been burnt down before he left the parish is 1869. O'Brien was then transferred to Cooma. He seems to have been administrator of St Benedict's parish, Sydney at sometime. He received a pension from the Colonial government, with an annual income of £150 a year.
On 22 November 1887, at the age of 70, he was admitted into the Society at the North Shore residence, and remained there until his death. He took final vows, 15 August 1898, two years before he died. In a photo of him in the 60s he appeared as a small man with a determined mouth, a high forehead, searching eyes light in colour, a finely chiseled nose and delicate features and small hands. He was an edifying old man, and full of zeal for the instruction of the people. He often preached at great length, and as he spoke quickly, the congregation found it hard to understand him. However, he was esteemed to be a holy man.
In the residence he was charged with the duty of ringing the bells for the various duties, and was remarkable for his punctuality He was rarely, if ever, a moment late in giving the signal. At one time he was dean of the Sydney diocese, and in his last years, spiritual father to the community.
