I have the same Leclerc Ancestors as you do. I apologise I do not speak French, but wanted to share with you what I have in my Database. I have Anselme Leclerc & Rosalie Caron married 1800/02/04 St. Jean Port Joli (Qc)
Anselme Leclerc & Marie Domine Bouchard married 1825/07/26 Riviere-Ouelle (Qc)
Joseph Norbert Leclerc married to Phebee Normand 1865/10/01 L'Islet (Qc) His second marriage was to Catherine Normandeau 1901/07/01 Carleton, Qc.
Then my Grandfather, Joseph Norbert Leclerc, Born - July 27/1862 St. Jean Port Joli, L'Islet, Qc.
He married my Grandmother Elise Babin on 1891/01/27 in Caplan, Qc. Both died from the Spanish Flu in 1918(?) leaving behind 11 children. I am still looking for the place where they were buried. Hope you find the information your looking for.
