Assuming they had live to old age, I have wondered what Tsar Nicholas II would have looked like in his 60's, 70's, at 80 years old. Same question for Alexandra.
Again assuming he had lived, what would Alexei have looked like in his 40's, 50's, 60's, or older? As he got older, perhaps as Tsar, would Alexei have worn a beard perhaps like his father?
What would Tatiana have looked like in her 30's, 40's, 50's, even older in her 60's, 70's or 80's.
Same question about Olga, Maria, and Anastasia.
Had these people lived it would be interesting to know what they would have looked like throughout their lives including late in life.
