Sæbbi of Essex
Sæbbi (also known as Saint Sebbi or Sebba; before 626 – 695) was son of Sexred and was the joint King of Essex from 664 to about 683 along with his cousin, Sighere. After Sighere died, Sæbbi became sole ruler of Essex until 694. Life. Sighere and Sæbbi were cousins of their predecessor, Swithelm. In 665 Sighere apostatized and fell back into paganism, while Sebbi remained a faithful Christian. They soon developed a rivalry. Sighere found an ally in Wessex, and Sæbbi in Mercia. As a result of their rivalry, King Wulfhere of Mercia established himself as overlord  of Essex in 665. He despatched Jaruman, the Bishop of Mercia, who was assigned to reconvert the people of Essex to Christianity. In 686, Cædwalla, a Wessex sub-king, established himself as overlord of Essex. He and Sæbbi invaded Kent, expelling King Eadric, and Sæbbi ruled over West Kent. It was presumably at the time that Sæbbi founded the original abbey at Westminster. Sæbbi is believed to have abdicated in 694 in order to enter a monastery, and was succeeded by his sons, Sigeheard and Swaefred, who ruled jointly over Essex. Another son, Swæfheard, would rule the Kingdom of Kent . Sæbbi died in 695 and was buried in Old St Paul's Cathedral in the City of London where he was revered as a saint. He is commemorated by Orthodox Church on Aug. 29 and in the Roman Martyrology also in the same day. Bede recounts the burial thus (4.11): Sæbbi's tomb survived the 1087 fire at St Paul's and his remains were transferred to a black marble sarcophagus in the mid 12th century. This sarcophagus was recorded in a series of drawings by Wenceslaus Hollar, published in Dugdale's "History of St Paul's". The tomb was  destroyed in the Great Fire of London. A plaque to Sæbbi was erected in the Wren cathedral.
