NN mac Causantín

a) son (-killed in battle [936/37]). The 10th century Pictish Chronicle Cronica de Origine Antiquorum Pictorum records that "filius Constantini" was killed in "bellum Duinbrunde" in the 33rd year of Constantine’s reign[97]. This date appears to coincide with the battle of Brunanburh in which Æthelstan King of Wessex defeated the invasion of England in which King Constantine participated (see above), although it is not certain that "Duinbrunde" refers to the same battle.http://fmg.ac/Projects/MedLands/SCOTLAND.htm#KennethIB
