Can you share his birth date and death date as well as the location of each? Location would be country, state or province, county and city.
If this is the profile you are referring to: http://www.wikitree.com/wiki/Charlebois-1
Then you can see under his name on the left hand side, the Profile Manager, with a link [send private message] .
If you click on that link, a page will come up where you can email Jamie directly with any questions you might have or to share your information. It seems Kelvin married her niece from what is written there.
