a lower status than the Saxons. This might have provided an incentive for Britons in the kingdom to adopt Anglo-Saxon culture. Higham points out that "in circumstances where freedom at law, acceptance with the kindred, access to patronage, and the use and possession of weapons were all exclusive to those who could claim Germanic descent, then speaking Old English without Latin or Brittonic inflection had considerable value." There is evidence for a British influence on the emerging Anglo-Saxon elite classes. The Wessex royal line was traditionally founded by a man named Cerdic, an undoubtedly Celtic name cognate to Ceretic (the name of two British kings, ultimately derived from *Corotīcos). This may indicate that Cerdic was a native Briton and that his dynasty became anglicised over time. A number of Cerdic's alleged descendants also possessed Celtic names, including the 'Bretwalda' Ceawlin. The last man in this dynasty to have a Brittonic name was King Caedwalla, who died as late as 689. In Mercia, too, several kings bear seemingly Celtic names, most notably Penda. As far east as Lindsey, the Celtic name Caedbaed appears in the list of kings. Recent genetic studies, based on data collected from skeletons found in Iron Age, Roman and Anglo-Saxon era burials, have concluded that the ancestry of the modern English population contains large contributions from both Anglo-Saxon migrants and Romano-British natives. Development of an Anglo-Saxon society (560–610) In the last half of the 6th century, four structures contributed to the development of society; they were the position and freedoms of the ceorl, the smaller tribal areas coalescing into larger kingdoms, the elite developing from warriors to kings, and Irish monasticism developing under Finnian (who had consulted Gildas) and his pupil Columba. The Anglo-Saxon farms of this period are often falsely supposed to be "peasant farms". However, a ceorl, who was the lowest ranking freeman in early Anglo-Saxon society, was not a peasant but an arms-owning male with the support of a kindred, access to law and the wergild; situated at the apex of an extended household working at least one hide of land. The farmer had freedom and rights over lands, with provision of a rent or duty to an overlord who provided only slight lordly input. Most of this land was common outfield arable land (of an outfield-infield system) that provided individuals with the means to build a basis of kinship and group cultural ties.
