I answer this question with a sourced reference but I would suggest
that an enquiry of the Cheshire Record Office be made to ensure its
The Anglo Saxon Chronicle on pages 66 and 67 referred to Wirheal, and
a local history site states that Wirheal is derived from the
Anglo-Saxon words for myrtle and an angle, corner or slope.
A couple of other sites agree with this, but the history of the name
Wirral does not appear in the Victorian Counties History or the
English Place Names Index.
Anglo Saxon Chronicle on pages 66 and 67
"...to the East-Angles, they marched on the stretch by day and night,
till they arrived at a western city in Wirheal that is called Chester.
There the army could not overtake them ere they arrived within the
work: they beset the...?
"...twelvemonth since they first came hither over sea. A.D. 895. Soon
after that, in this year, went the army from Wirheal into North-Wales;
for they could not remain there, because they were stripped both of
the cattle and the corn that..."
?But what of the name Wirral? Anglo-Saxon records show the peninsula
as ?Wirheal?, a combination of the Anglo? Saxon words wir (a myrtle
tree) and heal (an angle, corner or slope). From this it would appear
that bog myrtle was once plentiful in this area, although it is no
longer found today.?
