Hi Edna,
Yes I can confirm that Frederick Charles Ashworth (born 1835) became a licenced Liverpool Pilot in 1856.
The only other info says he became an Appropriated (choice) Pilot for Guion Line in 1870. This means that although still a Liverpool Pilot able to pilot any ship into, and out of the Port of Liverpool, if a ship of Guion Shipping Co was due to arrive or sail from Liverpool, then he would be released from the list to pilot one of their ships.
A complete record of F C Ashworth's Pilotage career can be found in the 'Pilot Character Book', held at the Merseyside Maritime Museum, Albert Dock, Liverpool.
Regards
Dave
