Hi,
There are 3 McAllister's in the list of Pilots.
1) G W McAllister (was it George William?) born 1851, licenced as a Pilot in 1870 and retired in 1917. In the 'Returns Relating to Pilots and Pilotage' for 1870 he is serving as an Apprentice Pilot attached to No 12 Pilot schooner "Perseverance", aged 19 and licenced to pilot vessels into Liverpool up to 250 tons. In the 1895 Returns he is a 1st Class Pilot, aged 44 and still attached to the "Perseverance" but she is now No 9. She was built in 1860 by T Harvey & Sons; 81'2"x18'x9'4";56grt. She became No 9 in 1885, withdrawn in 1896 and sold in 1898 for inter-island trade in the West Indies. In 1897 he is attached to Steam Pilot Boat No1 "Francis Henderson".
2) J McAllister born 1865, licenced in 1888, retired and died 1920.
3) Wm George McAllister, DOB 2/2/1882, date of admission into Pilot Service 13/9/1900 having spent 1 year 8 months sea service prior to this date. He joined Steam Pilot Boat No 4 "David Fernie" first but other records show that he also served most of his 'time' on No 3 "Queen Victoria". He was licenced as a 3rd Class Pilot on 1st June 1908. He was a very similar age to my own grandfather who joined the Service, amazingly enough, on the same date, namely 13/9/1900 along with a further 9 other candidates, although in my grandfather's case he didn't qualify until exactly a year later 1/6/1909.
A full history of their Pilotage careers can be found in the Pilot's Character Book at the Merseyside Maritime Museum, Albert Dock, Liverpool.
Hope this answers your question.
Regards
Dave
