Hi Autumn, have either of your parents tested their DNA? If not, that would be your first step. If they aren't available for testing, you would want to try and test one of their siblings (if they had any).
Since you tested with ancestry, have you started working/looking at your DNA matches to figure out your common ancestor? Start with the ones with the largest amount of shared DNA, as your common ancestor will be more recent than those that share less DNA. See if you are matching people up both your mother's and father's side.
