The well established Comín family for generations has been producing locally distinguished figures.
Jesus’ great-grandfather sided with Carlos V during the First Carlist War and sought refuge on exile afterwards.
His son, Bienvenido Comín Sarté (1828-1880), became a recognized lawyer, known as "el abogado de los pobres", and member of the Zaragoza ayuntamiento.
He sided with Carlos VII during the Third Carlist War, member of the Royal Council and leader of Junta Provincial Católico-Monárquica.
He too had to flee abroad; upon return he grew to a distinguished Zaragoza law scholar, Traditionalist thinker and writer.
Until death he continued as regional party leader in Aragon.

Bienvenido's son and the uncle of Jesús, Pascual Comín Moya, in 1919 briefly was the national party jefe, active among national Jaimista leaders until death in 1928.
Pascual's brother and Jesús' father, Francisco Javier Comín Moya (1857-1932), has not occupied major posts in the party, engaging rather in local Catholic periodicals like El Noticiero.
His prestigious position in the Zaragoza realm resulted from his stand as a recognized academic: in 1895 he assumed Cátedra de procedimientos judiciales y práctica forense of the University of Zaragoza and retained the position for the following 35 years.
In 1921 he became dean of the Facultad de derecho, the post held - since 1931 as honorary dean - until death.
Francisco Javier was married to Rosario Sagüés Mugiro; it is not clear how many children the couple had.

None of the sources consulted provides information on early education of Jesús.
Upon receiving bachillerato he entered Facultad de Derecho at Universidad de Zaragoza; his graduation in jurisprudence is not confirmed, though later on occasionally the press referred to him "abogado".
It is known, however, that he was excellent student in Filosofia y Letras, graduating in 1913 with premio extraordinario; at unspecified date he reached the grade of doctor in Philosophy and Letters, still in Zaragoza.

In 1920 Jesús Comín Sagüés married a Catalan, María Pilar Ros Martínez (1896–1973); the couple had seven children, brought up in fervently Catholic ambience.
The only one which became a nationwide known figure was Alfonso Carlos Comín Ros.
He gained recognition for theoretical attempt to merge militant Communism with Christianity, dubbed cristiano-marxismo; political prisoner in the Francoist Spain, he was one of the PSUC and PCE leaders.
María Pilar Comín Ros  and Javier Comín Ros were locally known in Catalonia as contributors to the Barcelona daily La Vanguardia; María Pilar ran the section on women's fashion.
Jesús grandson and Alfonso Carlos' son, Antoni Comín i Oliveres, is a Catalan Separatist politician.
He was the Minister of Health of the Executive Council of Catalonia between 2016 and 2017.
The older brother of Jesús, Francisco Javier, specialized in commercial law and served as catedrático in a number of Spanish universities; another one, Jose Maria, was active as Carlist politician, in the 1940s he joined Carloctavismo and in the 1950s recognized Don Juan as a legitimate Carlist heir.
