Merseyside South
On a Lancashire rose, a rose or bearing a liver bird vert (a cormorant, in the beak a branch of seaweed called laver)
The two words liver and laver hint a two theories as to the deivation of the name as a rebus or punning allusion to Liverpool. It is more widley accepted that the Norse "hlithar pollr" (the pool of the slopes) is the more likely derivation.
The bird appears on the common seal of the town. The original was lost during the siege of 1644 and the copy then made was so crude as to resemble a cormorant rather than the original eagle of St. John.
