He was a son of that Rodger Baskerville (он был сыном того Роджера Баскервиля), the younger brother of Sir Charles (младшего брата сэра Чарльза), who fled with a sinister reputation to South America (который с дурной репутацией сбежал в Южную Америку; to flee), where he was said to have died unmarried (где, как говорили, он умер неженатым). He did, as a matter of fact, marry (на самом деле, он женился), and had one child, this fellow (и имел одного ребенка, этого = известного вам человека), whose real name is the same as his father (чья настоящая фамилия была такой же, как и у его отца). He married Beryl Garcia, one of the beauties of Costa Rica (он женился на Берил Гарсиа, одной из красавиц Коста-Рики), and, having purloined a considerable sum of public money (и, похитив значительную сумму общественных денег), he changed his name to Vandeleur and fled to England (он изменил фамилию на Вэнделер и сбежал в Англию), where he established a school in the east of Yorkshire (где открыл школу в Восточном Йоркшире; to establish — учреждать, основывать).
