Looking for half brothers adopted through Baby Fold in 1977 and 1979

Looking for half brothers that share same birthmother as myself. I was born 5/10/1981 in Decatur, IL and adopted through the Baby Fold. I was given information at birth describing my birthmother and her family as well as the fact that she gave up two boys for adoption before me in 1977 and 1979 through The Babyfold. If anyone out there can help me out i would appreciate it. thank you
