My parents have never been married, my father wasn't there when I was born, as he was in Greece, so I just got my mums name. Then I chnaged it to my dads name so now I dont have the same name as my mum. -- Posted by crashdummi7 at 5:31 pm on July 6, 2009 i have a different last name then my mom -- Posted by xMoNoxLoCox at 5:31 pm on July 6, 2009 are his parents married?maybe hes not the biological dad? -- Posted by maddieface21 at 5:32 pm on July 6, 2009 Quote: from xMoNoxLoCox at 5:31 pm on July 6, 2009 are his parents married?maybe hes not the biological dad? yea i guess i never asked him. thanks. -- Posted by MajorT0M at 5:32 pm on July 6, 2009 Step Dad? -- Posted by aejae at 5:34 pm on July 6, 2009 maybe he took his mom's last name and his rents are split? -- Posted by Rawrj at 5:42 pm on July 6, 2009 Foster father?
