In the West Bank, the world's few remaining Samaritans are starting to marry women from outside to expand the gene pool.
Mount Gerizim, occupied Palestinian territories - Tanya's flat is surprisingly modern, her life surprisingly happy. Smiling out from behind her beloved cat, Tina, she joked about her sudden marriage to a foreigner.
"I told him the only thing I have to have is a cat," she beamed, standing in front an enormous wedding photo which hangs above the fireplace of her new home.
Around a year ago, Tanya left her native Ukraine as a bride bound for a tiny village in the northern West Bank. She had worked for only a few months at an agency in southern Ukraine matching women with foreign husbands when Kamel arrived, in search of a wife. After some attempts to arrange dates with her portfolio of potential partners, she finally consented to his persistent requests for her - and only her.
Kamel is a member of the Samaritan community, a religious group based in a small village near Mount Gerizim just outside Nablus city. They are known to the rest of the world from references in the Bible such as the story of The Good Samaritan - but not everyone is aware that they still exist.
They barely do. Today the Samaritans number just 766, according to their Priest Husney Cohen, though that's a lot more than in 1917, at the end of the Ottoman Empire when, he said there were just 146 Samaritans in the world.
