Judy Umlauf b Feb 12,1949 was my childhood girlfriend in Klickitat, WA. Her brother, Ricky was born in ~1947. Your grandparents, Herman Umlauf Jr and Marguerite Spalding married Nov. 25, 1936 in Goldendale, WA where Marguerite grew up. After Herman retired your G Grandparents, Selma and Herman Umlauf lived in my parents cabins 2 houses up from the river on 3rd Street and across the back alley from their daughter Alma [Umlauf] Westlund. I remember hearing Grandpa Umlauf sawing wood early every morning when I was 4 or 5 yrs. old.
Judy visited me ~15 years ago and we exchanged Christmas cards in 2009. When she visited I asked her about what happened to Ricky and she said that after he returned from the Vietnam war he became an alcoholic and she had gone through so much misery trying to help him that she wouldn't have any more contact with him. Judy's listed name in the white pages is 'Judith C Jones' in Aurora, Colorado. I just sent her a Valentine Greeting, but haven't heard from her since 2009. I've been calling her tel # and leaving messages, but haven't heard back yet.
You might try writing her Cousin, [Your 2nd cousin] -Fred C Hoctor, PO Box 911, Goldendale, WA 98620-0911. He is retired in Goldendale and is Judy's close friend. I'll let you know if I hear from Judy again.
