Respuesta :

Nicholas II is the son of Empress Maria who is married to Emperor Alexander. Empress Maria is the daughter of Louise of Hess-Cassel who is married to King Christian IX of Denmark. Nicholas II is the grandson of Louise of Hess-Cassel.

To find the descent, the line straight down from the marriage indicates the biological descent. Since both parents are known, the common descent is shown down from the marriage.
