This is the coat of arms of the nobel family Crichton.
The history behind this coat of arms very old. The use is also very old. I got the picture from a old relative in England who told me that the azur lion is rare in heraldics. Fidelis is latin and means fidelity, faithfullness or loyal. The animal head might be a camels head and therefore a reminder and symbol that some forefather took part in the crusade to the Holy Land in the Middle Ages.
If you happen to have more information about the history and meaning of this coat of arms I would be deligted if you informed me.
