George Vincent (painter) [SEP] Marriage and subsequent decline
No children are known to have been produced from the marriage. Vincent bought what the art historians Richard and Samuel Redgrave considered a "good house" in Camden Town, which was sold when, for reasons that have never been explained, his wife's money failed to materialise. By the summer of 1824 he and his wife were living at 26 Upper Thornhaugh Street, close to Bedford Square, a more affordable house closer to the centre of London. His health deteriorated and his debts mounted, in part because of his drinking habits. In a letter dated 27 July 1824 to his friend William Davey, he referred to a "past folly".
