Lincoln's Blood

[maharba]

I wonder if there is a reliable source of dna from blood or hair to get
Abraham Lincoln blood type, and any other useful blood antigen markers. Those dna testing sites talk about groups and haplo types. Then science
reaffirm the obvious: that Lincoln was from a Lincoln not an Enlow, and
which Hanks line it most likely points to. In the killing of Lincoln, of course, Booth came prepared and stabbed Rathbone with great loss of blood. Not to mention, there, the blood loss from president Lincoln.
