Brother Xavier’s work touched countless lives, spanned the generations and took him around the globe. He cared for newborn infants, the sick & dying, and everyone in between. Born Donald Arthur O’Neill in Wyandotte, Mich., one of seven children, he joined the Brothers of Mercy after graduating from high school without ever visiting the community. He professed his first vows on Sept. 8, 1945, and his final vows on Sept. 8, 1951. He studied at the Mercy Hospital School of Nursing, becoming a registered nurse and later a certified registered nurse anesthetist, which he considered to be his proudest accomplishments.

He first worked as a private duty nurse, making medical house calls day and night by bicycle. By the late 1940’s, the Brothers of Mercy had garnered a pristine reputation for compassionate healthcare, and their services were in high demand. Br. Xavier would work around the clock administering care, by providing pain relief and medications, as well as bathing and grooming his patients – all part of what the Brothers considered to be their ‘privilege to serve’. His compassion for his patients was boundless, and he always made it his mission to go above and beyond in any way that could, in his own words, “make them happy or touch their hearts”.

While caring for his aging mother, he was a nurse anesthetist in Detroit for 13 years, specializing in newborn care. In the 1960s, he served in a Brothers of Mercy Hospital in Africa. He also supervised a 100-bed Brothers of Mercy retirement home in Kansas City, Mo., and twice was a Brothers of Mercy Nursing Home Supervisor in Oklahoma City, Okla. From 1959 to 1963, he was Provincial Superior of the Brothers of Mercy North American Province in Clarence.

After retiring at the age of 91, he continued to enjoy fishing and travelling. Brother Xavier also spent much of his time praying for people and volunteering at Sacred Heart Home; some of whose residents can fondly recall him providing manicures there. An avid watercolorist, many of his beautiful paintings can be found throughout the Brothers of Mercy Campus.

His seven decades of dedicated service helped shape and evolve his sense of wisdom, knowledge and understanding of the world and others; though two things that never wavered were his good heart and dedication to helping others. Br. Xavier truly exemplified the mission statement of the Brothers of Mercy: “The Charity of Christ Urges Us On”. Survivors include two sisters, Rose Celine Cowan and Mary Ann Kowalski; a brother, Pat; nieces and nephews; and his fellow Brothers of Mercy.
