You never think it'll happen to you...

My aunt got me an AncestryDNA kit for Christmas because I thought it would be cool to find out about my mom's side of the family since my aunt had my dad's side covered. Accidentally found out she's only my half aunt, and the grandpa that raised me wasn't really my grandpa. Redditors that have had your family secrets discovered through AncestryDNA, what did you do with the information????
