In 1832, when he was only eleven, his mother, Geneviéve Benoit, died at the age of 32 years. His father remarried later that year.
Adele Guais dit Castonguais was also the great grandchild of a soldier who came from France to fight in the Seven Years War. That soldier was Martin Delmasse who fought in the Guyenne Regiment. She was also the great-great-great-granddaughter of Joseph Payan dit St.Onge, L'Admital de Lac Champlain
Here is one, followed by a closer view
Here is the other with a closer view
In the first image Solyme, Adele and their three girls: Mathilde 10, Cordelia 6, and Celenie are living with or in close proximity to Adele's parents Jean Guais/Guay and Angelique Delmasse. In the second larger image, Solyme and Adele with the same children are not in proximity to the Guais/Guay parents/grandparents.
We may safely conclude Solyme brought his family from Québec to Cohoes between the 1861 census of Canada and the 1870 US Federal Census. Perhaps the family moved after the marriage of Matilde in August 1962 but we cannot be certain. Solyme may have made the train ride north alone from Cohoes to St.Césaire for the wedding because the marriage document does not mention the presence of Adele, Mathilde's mother. Perhaps Adele remained in Cohoes with the children.
The last child in the family group is "Adolphine" who was born in Quebec in 1863....probably it was after Adolphine's birth when the family moved.
The Take Away....If you believe "Silliam Beoovah" is indeed the one and same as "Solyme Beauvais", you can believe the Solyme Beauvais family was established in Cohoes by the 1870 census.
