My brother's last name got changed about a year or two ago.Reason is....His last name was stevenson all his life but his mum's last name was wynne and his dad's last name was wilson.So it was best to get it changed to wilson,As me,sisters and other brother have wilson as there last name..P.s if your a little confused,He's my step-brother. Dont know if he paid for it though....He did had to go to a place to get it all sorted out etc etc...
