My succesful search began with my birth date. If your sister-in-law knows the name of the city and hospital where she was born, she may be able to do the same. I searched microfiche records at the local newspaper, and found there were just 2 girls born on the date shown on my birth certificate. Through the help of a co-worker who knew one of the families, I was able to eliminate that family. That left me with the names of my birth parents. Several years later, a long-time family friend filled in more info, including my birth father's name, current address and phone number. A week later, I drove just 75 miles to visit him and his wife. A relative, a long-time family friend, and the local newspaper brought me to the names of my birth parents. I wish your sister-in-law well in her journey to find her roots.
