Sylvain Pierlot werd geboren 19 december 1859 te Virginal en overleed in 1934 in Ronquières. Hij huwde met Augustine Gerardin, overleden 1949 te Ronquières. Uit dit huwelijk kwamen vier kinderen.
Sylvain Pierlot moved to France with one of his brothers to avoid military service. He met there his wife Augustine Gérardin from Le Havre. He could come back in Belgium because of an amnisty. He was well known as someone who liked to do jokes. He was ambulating merchant. According to Irène Devreux, his brother (which one?) didn't come back in Belgium and stayed in France.
If Sylvain Pierlot wanted to avoid military service, it was because he was injuried in the Virginal factory and the military administration didn't want to recognize the health problem he had because of that. He was so disapointed that he moved to France with one of his brother. This brother stayed in France as farmer.
