 Toirdelbach 's subsequent capture of Donnchad in Dublin suggests that the latter was not only the leading Uí Chennselaig dynast , but was also in the process of using the town as the capital of Leinster . Although the list of Leinster kings in the Book of Leinster declares that Domnall had succeeded his grandfather as King of Leinster , it is apparent that Donnchad was indeed the more powerful claimant . In fact , the king @-@ list of Uí Chennselaig in the same source makes no notice of Domnall , and states that it was Donnchad who succeeded Diarmait as King of Uí Chennselaig . Domnall , therefore , may not have reigned in Leinster , and could well have been King of Leinster in name only .
