if u find where u was born they may of put medical info in your records
i put my sisters there and only if she wants them they have all the info but dont have to use the contact info in them just the medical... hope that helps
also if you know where u was born and if the parnets was from there u could ask the hospital for more info and see if they can help you out. but that if you know who they are but dont want to contact them personally
