The
Orkneyinga saga says that Paul and Erlend (Erland) remained on friendly terms until their children grew to adulthood, after which the disputes between their sons led to a quarrel and open hostility between the brothers. As the disputes between the descendants of Paul and Erlend loomed large in the affairs of 12th-century Orkney, the saga went into some detail about their family relationships. Paul was married to an unnamed daughter of Norwegian earl
Hakon Ivarsson and they had two sons and four daughters. Of these,
Hakon Paulsson played the greatest part in later Orcadian events. Their other children were Thora, Brynjolf, Ingirid, Herbjorg, and Ragnhild. Erlend married Thora, daughter of
Sumarlidi Ospaksson. They had two sons and two daughters, while Erlend had a third, illegitimate daughter as well. The second daughter was called Cecilia, and the natural daughter was Jaddvor. Erlend's sons were Erling and
Magnus, who later appear in the saga as earl, martyr, and saint. Hakon believed himself to be the most highly born of the cousins and wanted to be seen as the foremost amongst his kin, but Erling was not one to back down. The fathers did their best to reach a settlement, but it became clear that they were both favouring their own offspring, which resulted in hostility between them. Eventually the earldom was divided into two distinct territories, as it had been in the time of their father Thorfinn and uncle
Brusi Sigurdsson. ==Religion==
