If you hyphenate a child's last name.....

[EponineVader]

Who's name goes first? The fathers or the mothers? Why? Does it matter?

Moms last name is. Hawkins

and 

Dad's is Smith...

Would the last name be Hawkins-Smith or Smith-Hawkins?

[Mama_Dolly]

I put my last name last* and dfs first, with no hyphen... so my son has two last names... because I am badass...

 No idea BUMP
