Coat of Arms?

Question:

Family Crests/ Coat of Arms?

Im looking for a coat arms for my family on my fathers side. My mothers side is Ripley and I have a coat of arms for Ripley, but I can't find one for my fathers side. His last name was Sanderson, but, (none of you will believe me but here goes) his great great great (I think it's 3 greats) uncle was Tsar (or Czar) Nicholas II. No joke.

Does anyone know if hw had a last name, or was he just called Tsar Nicholas?

Please help, and Im not making this up.
Please no jokes.
