Michael, I've been able to find only the marriage of one son from the 1st marriage in the BMS2000, v. 6:
Mazime SAULNIER (Cyrille+Rosalie CROZÉ) m. 1873-08-26 in Ste-Brigide parish, Montréal, QC to Célina PLANTE (Antoine+Rose LÉVESQUE).
No other marriages found for child with his wife | #.
Found marriage of one daughter from 2nd wife:
Délia BEAUSOLEIL (Cyrille+Delphine BEAUCHAMP) m. 1901-01-22 in St-Henri parish, Mascouche, l'Assomption County, QC to Damase DUPRAT (Damase+Héloïse CHAPUT).
DUPRAT is usually spelled DUPRAS.
Note given name of 2nd wife: DELPHINE & not Adéline.
That's all I could find.
Hope it helps you out a bit
