Do you think that the reason why when people get married the wife takes the husbands last name is down to a repressed Oediplus complex?

I just realised this when I called my (pretend) wife Mrs <insertlastnamehere> which freaked me out because it was my mums name and reminded me of the Oediplus complex (quick recap: man having sex with his mother). Am I overreacting or onto something here?
