Bfather was from Germany.

I was born in 1967 Oct.8th.My father was here in the states from 1966 to atleast 1967. He as far as I know has no idea about me.My bmom and bdad had a what is to believe a one night stand.My bdad was here from Germany on some kind of training exercise,then was sent back to Germany.So,as you can see I am not even sure that I am at the right site for this.?My bmom had a girl already when they met.The girl was about 6or7months old at the time I do believe.If anyone could help me that would be great.Oh yeah,The state they were in was Minnesota.
