Yes!
My identical-twin brother, Dean Jeffrey, was born about 3 minutes before I was. He had a nonpatent esophagus, and in late-1955, doctors had neither the knowledge nor the inclination to save him. He succumbed within a few days of profound malnutrition. Likewise, I had some birth defects too. Dean and I were premature and born to a woman of age 34 ... very late gestational maternal age in the mid-1950s. Today, medical science is advanced enough to be able to save a baby born this way. My records say the old man was a smooth-talking salesman and my birth mother was a petite and shapely secretary. They worked in the same office. My bro and I are the product of their intra-office, extracurricular, carnal dalliance. Today, this is no big deal. In the mid-1950s, it was shameful and scandalous beyond measure. You see, they were married to other people. Babies like my bro and me immediately got shipped off to the adoption agency. The times, they HAVE a-changed.
Mind you, I only found this all out a few years ago. You see, I'm adopted. For years and years, I had this strange, inexplicable feeling about my having a twin out there somewhere. That's the God's honest truth. The adoptive parents NEVER told me this ... or ANYTHING about my real history. I had to seek it out myself in later middle age.
Just imagine having that peculiar feeling for years that you have a twin out there ... and then finding out that you DID! An IDENTICAL twin. No joke. No lie. It happened. Now, is THAT freaky, or what? True story.
