Beginning the search

I plan to officially begin the search for my birth family, not because I dont love my family or need a new one because I have been overly blessed with my family but to satisfy a feeling inside. After having my daughter 2 years ago I have felt a void. I reliezed that she, and now my son, are my only 2 flesh and blood. I dont know much about my birth parents but I am determined and would appriciate any advice on searching one can give. I plan to track my journey and update here. Wish me luck!
