I have looked at Talbot's works. As children of Jos Roy and Cath. Fradet who got married in the nearby counties, he has:
Jos. who married Cath. Gontheir
M1: Gervais Borchu
M2: Louis Dallaire
Alexandre: married Malvina Labrecque
Diogene who married Esther Chabot.
If there was a son name Regis, he may not have reached adult life or never got married, or got married outside the surrounding counties or emigrated to another region or country.
