This is a very interesting article:

The article is about research following an archaeological excavation in Dorset of 57 skeletons of people living around 100 BC to AD 100. Some extracts from the article:
"Skeletons unearthed in Dorset contained DNA evidence that Celtic men moved to live with their wives' families and communities."
"Scientists found evidence of a whole community built around the female line of a family over generations, probably originating with one woman."
"The work indicates that this society was what is known as matrilocal - meaning that a married man moved to live in his wife's community."
" "The most sort of obvious benefit to a woman is that if you don't leave home, you don't leave your support network. Your parents, siblings, family members are all still around you," says Dr Cassidy."
"Matrilocal societies are also less likely to experience internal conflict, she says."
" "It can promote feelings of unity among neighbouring communities and villages. It disperses groups of related males, stopping groups of related males developing strong loyalties and starting feuds with the related males nearby," she suggests."
