How do I find my ancestors

pernille christoffersen

I am from Denmark and am in the process of helping my sister-in-law make her family tree.
In that regard, I have found out about her grandmother's brother, who emigrated to canada.
My sister-in-law always knew he had left for Canada and that he had two boys.
I have now found his death and the death of his wife, as well as the names of both boys.
I want to hear if there is anyone who can help me find the parents' wedding
and the mother's birth (if anything is mentioned about it at their wedding.
These are Leo Robert Hansen born 17 June 1899 in Denmark and his wife Sophia born Schultz.
I do not know anything about Sophia, so if anyone could find anything about her, I would be very grateful
I know they had two boys - Robert Henry Hansen born November 4, 1935 in Saskatchewan, Canada.
The other son was named Don Hansen - I do not know when he was born. 
If anyone could help me with information about their birth and infant baptism, then that would be great
I know that Robert Henry Hansen married a Dorothy Louise Nicolson for approx. 1962
They had 4 children - 2 boys named Patrick and Robert, and 2 girls named Barbara and Donna.
I know Robert Henry Hansen died on August 28, 2009 in Saskatchewan.
His wife Sophia Schultz died on April 27, 2013 in Saskatchewan.Her parents were Charles and Blanche Nicolson.
This was a lot of information and questions, but I hope there is someone out there who can and will help me with a little more information
Thanks in advance from Pernille in Denmark

Have you tried http://genealogy.ehealthsask.ca/vsgs_srch.aspx a genealogy index search for birth/marriage/death - although marriages aren't available.

Also try looking at the Saskatchewan records available through FamilySearch https://www.familysearch.org/search/location/canada/saskatchewan
