Looking for Birthfather

I have no clue if this man even knows about me, but I have been looking for him forever. I was born in Feb or March of 1967 in Seattle Washington University of Wa hospital, I was 2 months premature to a woman by the name of Theresa. She gave me the name of Carmella which has since been changed. My b-father was 25 years of age when I was born. He was of German lineage, a roman catholic, has a twin sister and 3 other brothers and was a dental assistant and baker in the army. I am not sure where he was stationed. My father was 6' tall, light brown hair and possibly born in 1942. my mother was of Italian lineage, born in 1945, was a beatician, has a brother and her father died of cancer before my birth, she was 5'2" 130 pounds dark brown hair brown eyes. Mother is from somewhere back east. If any of this information sounds familiar to anyone, please contact me. Thank you
