Cumméne Find was a kinsman of Columba from the royal dynasty of the Cenél Conaill.
[1] He was the nephew of a previous abbot, Ségéne mac Fiachnaí and great-nephew of Lasrén.
[3] Finan of Lindisfarne died in 661, and Cumméne Find sent Colmán to succeed him as the third abbot.
[4] It was during Cumméne's abbacy that the Northumbrians decided against adopting the Gaelic dating of Easter at the Synod of Whitby in 664, resulting in the loss of control of the Ionan offshoot Gaelic church at Lindisfarne.
[5] The text was later inserted into the Schaffhausen manuscript of Adomnán's Vita Columbae for political reasons in the script of the early eighth century.
