Looking for Information

Hello All, On June 9th I learned that my Mother gave a son up for adoption 4 years before I was born. Since June 9th I have spoken to my sibling. We are planning on meeting in the next few weeks as we only live about 2.5 hours by car away from each other. Looking for any information. Have lots of question and am looking forward to meeting him, his wife and children. Any info is appreciated. Right now I feel like I am in a made for TV movie. JD
