Like his brothers, Severin was also a servant when he went to the Wetteren ten Ede town-hall to join the military. However, he only stood only 1 m 602 mm and was unsuitable because he had incurable scrofulous tumours. In 1846 he lived as a servant on the "Plaets 135" with Pieter De Bruyker, a farmer. On July 1850 he moved to Laarne where he married on Sophia De Vos, natural daughter of Coleta De Vos, on April 15, 1858. Sophie De Vos signed the certificate but Severin couldn't write his name! Sophia and Coleta were farmers and Severinus also became a crofter. He lived with his wife and mother-in-law on Ascopstraat where his five children were born (1).

Coleta De Vos died in 1874 and the same year her daughter died on June 19. Severin left Ascopstraat and went to the Quastraatje in the same municipality. There he died on February 16, 1882, 67 years old.
