Please post the wikipedia link if you want to have a discussion about it.

http://fmg.ac/Projects/MedLands/SCOTLAND.htm#KennethIB has his death as (-after 911)

there, as here
2. [DONALD . King of Strathclyde. The 10th century Pictish Chronicle Cronica de Origine Antiquorum Pictorum records the death of "Doneualdus rex Britannorum", during its record of the early part of the reign of Constantine II King of Scotland, and the choice of "Duuenaldus filius Ede" to succeed him, "et Flann filius Maelsethnaill et Niall filius Ede"[124]. Some secondary sources show Donald as the son of Aedh King of Scotland. He is shown above as the possible son of King Aedh’s sister who had possibly married Aedh King of Ireland.] http://fmg.ac/Projects/MedLands/SCOTLAND.htm#Aedhdied878B

his parentage is doubted

In any case, I'll update and lock the death date. Thanks for spotting.
