The name Abel suggests Abe L. — that is, Abraham Lincoln. Lincoln was murdered (though not by his brother), and he presided over the Civil War, often described as fratricidal. A number of coincidences link Lincoln to John F. Kennedy — Kenn and Abe L.
Another name that sounds like Abel or Abe L. is A. Bell — Alexander Graham Bell. The missing portions in those two abbreviated names also match quite nicely. Abe is short for Abraham, and A. Bell’s middle name was Graham. The biblical Abraham’s original name was Abram, and the name Graham is often pronounced “Gram.”
Bell’s statue also looks an awful lot like Lincoln’s.
