Kaðlín HRÓLFSDÓTTIR (c. 880- )

There may be circumstantial evidence for kinship between Rollo and his historical contemporary, Ketill Flatnose, King of the Isles – a Norse realm centred on the Western Isles of Scotland. If, as Richer suggested, Rollo's father was also named Ketill and as Dudo suggested, Rollo had a brother named Gurim, such names are onomastic evidence for a family connection: Icelandic sources name Ketill Flatnose's father as Björn Grímsson,[23] and "Grim" – the implied name of Ketill Flatnose's paternal grandfather – was likely cognate with Gurim. In addition, both Irish and Icelandic sources suggest that Rollo, as a young man, visited or lived in Scotland, where he had a daughter named Cadlinar (Kaðlín; Kathleen).[24][25] Ketill Flatnose's ancestors were said to have come from Møre – Rollo's ancestral home in the Icelandic sources. Ketill was a common name in Norse societies,[26] as were names like Gurim and Grim.
