Have you considered the source of the "whisked away" story? www.familytreedna.com
Not scientifically-sourced, but note:"...2 percent to 5 percent of the U.S. population is born with red hair, due to the recessive nature of the gene that produces it. That gene, the melanocortin 1 receptor, was discovered on the 16th of the 23 human chromosome pairs in 1995 by Jonathan Rees, a professor at the University of Edinburgh in Scotland."
You could get a library book about Mendel's early genetic studies of inherited features, but now things have become more complicated with DNA and polychromosomes.An expert person just told me that both your natural parents had tohave had recessive red hair genes.Any of your 4 grandparents could have been carriers of the red hair gene, and all could have had non-red hair.Same goes for your 8 great-grandparents.
Any parents who wanted to switch babies would have needed the power & access of the King of Old Medieval England, to have carried off such deception!There was an infant skeleton found in the walls of Windsor Castle (I think it was) during re-construction in the 1970s --- believed to have been the real royal heir, and switched for a healthy baby boy.
However Broward General is a large modern hospital.My understanding (having had 6 children) is that the nurses and doctors ALWAYS whisk away the babies to weigh, measure, footprint and apply various medications and wristbands!
