My mom married my dad shortly before WWII. His name was Otto Vokacek. She divorced him when I was about 3 and married my step-dad, the only father I ever knew. I have very little recollection of my birth dad. I do remember him showing up once when I was about 10, but he never paid a dime of child support or ever sent me a birthday present or card. When I was about 27 I got a letter from his new wife informing me of his death and inviting me to his funeral in Oregon. I decided to attend, although he had never attended my life.
Well, I met his two brothers (my uncles) and my two half sisters. I understand that one of my half-sisters committed suicide several years ago. I would like to find my other half-sister. My motive: Well, I have a daughter (also an only child) and I would like her to have some connection to my side of her family, since my mom and step-dad are dead and I am an only child. She is also estranged from her father. Any help on how to find this info would be appreciated. Thanks!
