I thought the male was my bio-father and he isn't. How do I delete him and his entire side of the family?
If you added him as your father you only need to delete that relationship. Click on the edit icon on the individual you want to remove from the family relationship. You can remove or replace the individual you want to change. I hope this helps.
you rarely if ever delete people - what you do is disconnect relationships
here is a link about correcting relationships
If these are deceased individuals it would seem a shame to delete them, as their addition (by you) to Family Tree might later be of great use to another researcher. However, provided you have created these IDs, and no other user has added any input, you are perfectly entitled to delete them, but this would have to be on a one-by-one basis.
As Dennis suggests, detaching relationships is probably the best - and easiest - way to deal with this situation.
Do not delete, just unattach. So go to the man's page where you appear as the child. Click on the edit icon by your name and click on Remove or Replace next to the man's name. You should end up with your mother but no father.
