I stumbled on this post after coming across other references to Fr. Francis Griffin C.S.Sp.:

GRIFFIN, Fr Francis 1893-1983
Born 16 September 1893 in Kilmurry, Ibricken, Co. Clare, Frank came to Rockwell as a boarder in 1907 and later entered the Juniorate where he was a contemporary of Liam O'Flaherty, the well known writer. He entered the new novitiate opened in Kimmage in 1911 together with future archbishops Charles Heerey and James Leen. Professed in 1912 he studied Irish and French at UCD and prefected at Blackrock, 1913-16. During the Easter Rising 1916 he was confined to the infirmary with an attack of pleurisy. He was later sent to Switzerland to do his studies for the priesthood. Ordained in 1920 he obtained the STL at Fribourg university in 1921. Fr Frank's first appointment was to the Irish senior scholastic where he taught Moral Theology for a year before being transferred to Rockwell, then badly in need of new blood. He served for three years as Dean of discipline,. Because of his diminutive stature he was soon known to the students by the name 'Tiny' - a name by which he was to be widely known throughout the Congregation during all his long life. His life-long close friendship with Dr Dan Murphy, which began during their student days, was further cemented as they tried to revitalise Rockwell at this period. In 1925, however, Fr Griffin's services were required once again in the senior scholasticate, and in the following year the newly appointed Vicar apostolic of Kilimanjaro, Bishop Henry Gogarty, invited him to his mission in East Africa. He worked at Arusha for two years and at Kilema for five. He was superior of Kilema and Pro-Vicar Apostolic from 1931 to 1933. In June 1933 he was elected General Councillor and took up residence at the Mother House in Paris as from March 1934, having administered Kilimanjaro Vicariate between the time of the death of Bishop Henry Gogarty in 1931 and the arrival of Bishop Joseph Byrne two years later. Fr Griffin remained in Paris throughout the Second World War and was appointed Assistant General in January 1949. On 26 July 1950 he was elected Superior General, the first non-Frenchman to hold that post. Under his guidance the Congregation picked up the threads disconnected by the war, and the provinces of France, Germany, Belgium and Holland were rapidly built up. Contact was also reopened with the province of Poland after a personal visit there by Fr Griffin. One of his first official actions was to recall Dr Dan Murphy from East Africa and to appoint him Procurator General at Rome; he was the first non-Frenchman to occupy that sensitive post. New foundations were started in Spain and Canada. Colleges and seminaries were built. He helped missionaries to adapt to the changes prompted by decolonisation. In recognition of his services he was awarded degrees of Doctor of Laws by the University of Duquesne and by NUI. He was noted for the simplicity of his life-style as Superior General. He was a strict upholder of the rule as then approved and his rather prompt decisions delivered in a gruff voice made him seem insensitive to those who did not know his manner. He was also seen to be less easy of access than other Superior Generals in modern times. When his term of office ended in 1962 he stepped back into the ranks, joining once more the staff of Rockwell College where he taught French and other subjects. He continued his work almost up to his death. He was to become a well-known figure on the school grounds, much liked and respected by the students as well as the staff. He was an inveterate long walker which kept him remarkably fit, and he kept an open mind as he witnessed the changes happening all round him. In fact, like a good brand of the whiskey which he appreciated on social occasions, he was seen to improve with age. His confreres got to love him as a man of great simplicity and fraternal understanding. The final summons come rather suddenly. Fr Francis Griffin died 6 September 1983 when he was aged 89 years. He was buried in Rockwell And as he was always a keen supporter of 'an teanga dúchais' we conclude with: Ar dheis Dé go raibh a anam dílis. IPNl No 54, September 1983.
Fr. Griffin was the son of John Griffin and Margaret Corry or Curry.
According to their marriage certificate at
https://civilrecords.irishgenealogy.ie/ ... 191843.pdf
John (who was 30 when married in 1869, 68 in 1901 and 81 in 1911) was the son of another John Griffin. He came from Tromra and married into the Corry/Curry place in Shandrum. Margaret's father Anthony Corry emigrated to New York leaving his daughter in Ireland.
I cannot see how they are related to Michael Griffy and Bridget Murrihy.
The Wikipedia article confirms that Fr Griffin was succeeded as head of the Holy Ghost (now Spiritan) order by the somewhat better known Archbishop Lefebvre.
