I think I understand what you are going through with your new discoveries because of my history. Though our stories are nothing alike, I know what it was like when at 12 yrs old my grandmother had the foresight to bring me to Italy and give me an entire part of my family that, though I knew existed, I had no real connection with. They welcomed me with open arms and ever since they have been as much a part of me and my life as the family in the US is.
