Sorry if this has been asked before but it's really bothering me. Okay, so what happened to Hermione's parents after Voldemort was defeated?

She had previously put the Obliviate spell on them so they wouldn't remember her o themselves and then they'd be safe. but after the threat was gone, what happened to them? are they still vacationing? did she never try to contact them again? even if she did contact them, they wouldn't know who she was. so did she effectively orphan herself that día when she obliviated them?
