Mark Tapley is the body-servant to Martin Chuzzlewit.
According to his biographer Charles Dickens, he is first traceable as an ostler for the Blue Dragon Inn in Salisbury, and is in love with the widowed landlady Mrs Lupin. He departs the pub and goes to London shortly after this first appearance.
When Chuzzlewitt arrives in London to emigrate to The United States, he meets Mark, who offers himself to be Martin's travelling companion and servant.
After Mark and Martin are swindled into buying a marsh along the Mississippi, they return home to England. Mark gets engaged to Mrs Lupin, takes over the Blue Dragon Inn and renames it the Jolly Tapley. He is then lost track of.
His manuscripts were found in Paris, where he is believed to have traveled at least twice before his death on the road sometime around 1883 (he would have been aboout 70 by then) .
