just almost seems out of place, unless thats what -san, -chan, -kun are for, but what do you do if you're speaking to parents, same last name, use the mothers maiden last name?
-San, -Kun, -chan etc etc
are Honorary names added behind the name of the person.
-San = Usually used out of respect of each other, and both are not close enough.
-Kun = Usually used for Younger Boys, or male that you think is close to you
-Chan = Same with Kun, only it's used for girls.
Adding those will show feelings from respect or a close relationship.
About parents in JApan
They strictly use Otou-san and Oka-san/ Chichiue and Hahaue. It's disrespectful for calling them with they're given names, or even maiden names.
