The remains of the last 2 Romanov children were discovered this past summer, further putting to rest the question of what happened to the family after the violent Bolshevik revolution in 1918. Prince Alexei and Princess Maria were found in a field near Yekaterinburg, Russia. A story on CNN has all the details.
The other 5 members of the family were unearthed in 1998, and now the entire family is accounted for. There have long been speculations that various members may have escaped execution, but now that is known to be untrue. Genealogically speaking, the Romanov family is best known for how the disease hemophilia touched the family (in Prince Alexei) having been handed down through the family from Queen Victoria.
