Searching for children of Ruth Wooster

Thanks to the new law in NH, my friend was able to connect with his mother and 4 of his siblings. His mother had 5 other children whom we haven't found yet. Their first names are/were Sandra, David, Archie Jr (or Michael) and Rosemarie plus a girl (the youngest) who was put up for adoption at birth as was my friend who was the oldest. If you have obtained your original birth certificate and your mother's maiden name is listed as Ruth Wooster, she and your brothers and sisters are looking for you.
