Please help I'm a newbie

Let me start by saying Thank You to everyone involved with this site. It is so wonderful to know there are people out there that feel the same way I do & I am not alone. Things can be said here that I have been afraid to voice all these years because I didnt think I had the right to. Now, with that said I need advise. I am a 42 year old adoptee. I was placed with my adoptiveparents when I was only 5 days old. It was a private adoption but I am from a small town & rumors flew as to who I belonged to. Once I was told that a girl in the neighboring town was my sister, I blew it off, after all my Mom didnt even know who my birth mom was. She only knew my last name was Hughes. My Id bracelet had been left on & she saw it before they cut it off. Years later my best friends Dad told her he was certain he knew who I was but wouldnt tell. After his death her grandmother said I was related to her & that I was the oldest of 3 girls, all put up for adoption at birth. The girl I had been told about years ago & another one that would be the youngest. Again, I blew it off because the last name didnt match. Later while facebook stalking, I found that these 2 girls have found each other! Now I wonder if I am their sister. The birthmom was a Brock but a friend of the family says she thinks that the Brock dated a Hughes. Would they have put the birth dads last name on my Id? Now I dont know what to do. I sent off for both identifying & non identifying info in Dec. In Feb. 2011 I received notice from the state of Va that my info was being sent to my county of birth & I should hear something within 8 months. The waiting is killing me. Should I continue to wait or make contact & ask directly if they have any info on a 3rd child. Both of these ladies are in touch with the birth aunt on facebook. I have thought about contacting her directly. Any input would be greatly appreciated.
