Female adoptee born 6-13-72 iso birthfather who lived in Great Falls, MT.

I am searching for my birthfather. I was born 6-13-72 in Great Falls, Mt. at the Deaconess Hospital. My birthmoms name was Virginia Warren and she was 19 at the time of my birth. My birthfather was 24 years old and had blue eyes, long dark curly hair and a beard. He had completed 9th grade and served two years in Vietnam with the United States Army. His father was 55 years old and worked as a railroad policeman here in Great Falls and his mother was 50 years old and worked at Buttreys Grocery Store in Holiday Village Mall. If you have any advice or if this sounds familiar to you please let me know. You can private message me or email me if you dont want to post here. Aura:)
