Merewalh
Merewalh (sometimes given as Merwal or Merewald was a sub-king of the Magonsæte, a western cadet kingdom of Mercia thought to have been located in Herefordshire and Shropshire.
Merewalh is thought to have lived in the mid to late 7th century, having acceded the throne during the time of Penda of Mercia, who, the "Anglo-Saxon Chronicle" implies, was his father :
The name Merewalh signifies "Famous Foreigner" or "Celebrated Welshman", possibly indicating that he, and perhaps even Penda's dynasty, was of Celtic origin.
During his lifetime, Merewalh converted to Christianity in about 660, founding Leominster Priory.
Merewalh married Saint Ermenburga, having several children (see below).
He died sometime between 670 and 685, being succeeded by his son Merchelm.

The three sisters have been likened to the three theological virtues: Mildburh to faith, Mildgyth to hope, and Mildrith to charity.
She was a Benedictine nun and later abbess of a Northumbrian convent.
All that is known of St Mildgytha was that she was a nun and that “miraculous powers were often exhibited” at her tomb in Northumbria.
She seems to have died long before her sisters, while still quite young, which may account for so little mention of her.
Her feast day is 17 January.
