  Notes	Fiacha Baicheda mac Cathair Mór of the Uí Cheinnselaig, the son of Cathair Mór, was a 5th century King of Leinster. [1] Fiacha was the son of Cathair Mar. [2] Research Notes This profile seems to be conflated Fiacha Baicheda fl 100 son of high king Cathair Mór and 5th century King of Leinster. This profile is based on Jaski's table 38 and many other historical sources and DNA backed family lines. Fiacha's Birth date (DOB) is based on his son's DOB. His father Cathair Mór mac Feideilmid (abt.0090-abt.0122) date of death does not match. More research is required.
