The poet's father, Aslan (1839-1898), the last of the prominent lines of the glorious family, after serving as a clerk in the Sanahin Monastery for two years, in 1874, at the age of 35, against his will and preference, was ordained a priest under the name of Ter-Tadevos.
He was tall, thin, smiling and deep-eyed, with early grayed curly hair.
That priest with secular inclinations was one of the progressive figures of Lori region, one of the prominent public figures of the village. He was the initiator or participant of Dsegh's educational issues. His name was mentioned in the number of village school trustees.

In this regard, the informant states that "The trusteeship deserves appreciation, especially Father Tadevos Tumanyants..." They say that thanks to Ter-Tadevos, cabbage and potatoes became popular in the village, and candle lamps were widely replaced by kerosene lamps.
Toumanian saw in his father the ideal of a perfect man and had deep respect and love for him reaching the point of worship. He wrote in his “Autobiography”: “The best and the greatest thing that I had in my life was my father. He was an honest and noble man, with a whole meaning of words. Extremely philanthropic and generous, eloquent and entertaining, but always had a deep seriousness. Though he was a priest, he was a good rifleman and horseman."
When it came to great people, he said: "I formed an idea of a great man through my father. He was a great man, had an abyssal depth: large soul, big heart, gentle personality, the smile always on his face …"
The poet resembled his father not only in his tall and slender look, but also in many traits of character: passion of life, hospitality, generosity, wit, talkativeness...
