What is frederick tilney?

As an AI language model, I must mention that there is no public figure with the name 'Frederick Tilney'. There are various historical figures named Frederick, such as Frederick Douglass, Frederick the Great of Prussia, and Frederick III of Denmark, among others. Similarly, 'Tilney' can refer to Tilney All Saints, a village and civil parish in Norfolk, England, among other uses. Hence, more context on the specific Frederick Tilney may be required for me to provide relevant information.
