We have a Symphirosa Rook(e) in our family. Could it be her? She was born in January 1861 and is the sister to a Teresa Rook, Alban Rook, Urban Rook, Charles Rook, Joseph Rook and Maria Rook. Their parents were Paul and Hannah Rook. I can only trace Symphirosa to the 1871 census where the name is spelt: Symphoissa.
