Gerald Thomas Morahan, the youngest of the five children of Michael J. Morahan and Emily M. Logan, was born in Denver, Colorado, on September 15, 1926. His early education was at St. Dominic Grammar School and then at St. Joseph High School, both in Denver. He then attended Loras College for a year before entering the Dominican novitiate at River Forest, Illinois, in September of 1945, where he received the religious name of Bertrand.

On September 20, 1946, he made his first profession at St. Thomas Aquinas Priory, River Forest, Illinois, and remained there for his philosophical studies (1946-49), obtaining a Bachelor of Philosophy degree from the Pontifical Faculty of Philosophy. On September 20, 1949, he made his solemn profession of vows and began theological studies. In September of 1951 he was among the group of theological students who moved to Dubuque, Iowa, to open the Province's new house of studies for theology. He was ordained a priest on May 22, 1952, at St. Rose of Lima Priory, Dubuque, Iowa, and completed his theological studies in 1953.

Father Morahan spent his entire priestly ministry in parishes of the Province. His first assignment was as an associate pastor in the home missions at St. Margaret Parish, Boyce, Louisiana (1953-56). In 1956 he was assigned as an associate at St. Vincent Ferrer Parish, River Forest, Illinois, and then as an associate at Holy Name Parish, Kansas City, Missouri (19 58-70). During his twelve years at Holy Name Parish in addition to his work on the parish staff he was Director of the Shrine of Our Lady of the Rosary of Fatima where he regularly broadcast the recitation of the Rosary over a local radio station. In conjunction with his Shrine work he served the Province first as Director of the Confraternity of the

Most Holy Rosary and then as Provincial Director of all Dominican Confraternities. It was also during this period of ministry that he taught for a time on the faculty of Lillis High School and was a regional promoter of vocations for the Province.

In 1970 he was elected Prior of St. Vincent Ferrer Priory, River Forest, Illinois, a position which he held for six years, and at the same time served as an associate pastor at the parish. Following his service as Prior of the community, he continued on there as an associate pastor and in 1983 was asked to join two other Dominicans to begin ministry at a new parish, St. Gertrude's, in St. Clair Shores, Michigan. He served there as an associate pastor until his death.

As early as 1981 Father Morahan was diagnosed with severe heart disease, yet he continued in parish ministry. In May 1998, his doctors decided that another heart surgery was warranted; he entered the hospital for the surgery but did not recover and died on June 4, 1998. A wake and funeral liturgy were celebrated at St. Gertrude Parish, St. Clair Shores, Michigan, his body was then taken to Denver, Colorado, where on June 9, 1998, a funeral liturgy was celebrated at Immaculate Heart of Mary Church followed by burial in the Dominican plot at Mt. Olivet Cemetery, Denver, Colorado.
