Tale of Two Brothers

This is a true story about two non-identical twin brothers who were adopted soon as they were born due to unfortunate circumstances. They were taken up by two different families who happened to be in the vicinity of about ten miles from each other - none of the two families knew each other. Everything was running smoothly until circumstances led one of the boys to search for his biological parents and his other brother. How successful was he? Was it like looking for a pin in a haystack in the wide world? It was many years, according to the foster parents, since he had been adopted - there had been a lot of tear jerking moments.
