In the following two years Liszt and Marie travelled widely in pursuit of his career as a concert pianist. Late in 1837, when Marie was heavily pregnant with their second child, the couple were at Como in Italy. Here, on 24 December in a lakeside hotel in Bellagio, a second daughter was born. They named her Francesca Gaetana Cosima, the unusual third name being derived from St Cosmas, a patron saint of physicians and apothecaries; it was as "Cosima" that the child became known. With her sister she was left in the care of wet nurses (a common practice at the time), while Liszt and Marie continued to travel in Europe. Their third child and only son, Daniel, was born on 9 May 1839 in Venice.
