Long lost biological son

Hello,
My name is Perry, I am looking for my biological father. I was born in Columbus, Ohio in April 1979. My mothers maiden name is Viveta Neilands. My parents attended Walnut Ridge H.S. I don't think he graduated but should have been in the class of 73' or 74'. My fathers name was Robert Gately Jr. From the information I have gathered his father was Robert Gately Sr., he was Irish and German. His mother was full Japanese although nobody can remember her name. My father also had a sister I think her name is Cathy. If anybody from the Gately's would contact me it would be greatly appreciated. I would really like to meet my father or at least visit his grave. Any contact from other family members would be great, it would be nice to know if there are any inherited health issues.
Thanks and God bless.
