Maxim Vachon-Savary is a "hyphenated Quebecker" who carries around the surnames of both his mother and father. When he and his wife had twins last year, they had to make a tough decision.
He and his wife, Veronique Chayer, were legally allowed to choose from eight different name combinations for their twins. It could be Chayer-Vachon, Savary-Chayer, Vachon-Savary, Chayer -- and the list went on.
In the end, the Quebec City couple settled on a single choice. Their girls' last name would be Savary, the same as Mr. Vachon-Savary's father. [Link]
