Come on Bob! The White Ensign is flown by commissioned warships. The Red Ensign by merchant vessels and the Blue Ensign by merchant vessels where the master holds a Royal Naval Reserve commission.
The Union Jack is normally only flown by naval vessels at the bow of the vessel while in harbour.
If your Jeannie Deans is depicted at sea on war service under the RN she would be flying the White Ensign.
