The midfielder was born in a family where football was omnipresent. His father, Deben Singh, was a football coach and a constable in the Manipur Police, taught him about football and its language. He was just four years old when he started playing football on a small ground in front of his house. Jeakson was a bright student, good at academics, and his parents wanted him to become an IAS officer, which he didn't agree to at all.
His brother, Jonychand Singh, is a footballer, and his cousin Amarjit Singh is also a professional football player. Jeakson Singh family supported him amid all the financial crises they faced. His mother, Bilashini Devi, sold vegetables and is also a weaver, working hard to support his dreams in football. His father had a stroke and needed to leave his public service job, and now he works as a farmer, and his brother became the main breadwinner. Jeakson started training at the Chandigarh Football Academy first, which was very far away from home, and later moved to the Minerva Academy. He even became the captain of the Minerva club and won the AIFF Youth Leagues twice for the Under-15 and Under-16 levels.
There is no public information about Jeakson Singh girlfriend. The footballer seems to be single.
