Unfortunately those come from different services and might be linked to your registered name on your carrier or legal name registered in licenses. If the info comes from your carrier, you need to check with them. If the info comes from those 'Caller ID' apps, you'd have to know which service (usually 3rd party or 'crowdsourced') it's using. Or maybe they just have your contact information saved on their phones already with that last name.
