Arthur raised an eyebrow. The Malfoys. He knew that many believed that the Weasleys had a blood feud with the Malfoys due to a broken marriage contract, but in reality, it was a side branch of the family that was feuding with the Malfoys, because they had refused to fulfil a marriage contract with the Malfoys and the member married a muggle instead, which had caused to worsen the relationship with the Malfoy family and the main branch of the Weasley family. He knew that the main branch, where Arthur was descending from, demanded from that member to make amends with the Malfoys, but the man was a coward and ran off with his wife and children into the muggle world. So, the main branch disowned him and his children from the family, pleasing the Malfoy family slightly, but then the side branch started a blood feud with the Malfoy family and cut all ties with the main branch since they knew that they wouldn’t get any support from the main branch due to the fact, how they had treated their former member and his family.
