1938 Mary Goodwin birthmother - Oregon

I am searching for my dad's birthmother, Mary Dolores Goodwin. She gave up my father through Catholic Charities in November 1938. She was Married to a Harry Edward Miller. They were living in Eugene Oregon. She found out after she became pregnant that he was already married. She was a schoolteacher. She went to live with relatives in Washington while she was pregnant from the information I obtained. She was born around 1915 and Harry around 1910. He was born in Minnesota from the birth certificate. Any info would be appreciated. I just want to tell her what a great life my dad has had and would really like to meet her or any other family. Thank you. Molly
