However, Listing's family life did not go well. The couple had two daughters - one in 1848 and the second in the following year. However Pauline Listing's :-

... treatment of servants brought her before the magistrates any number of times, while her relations with landlords led to many moves for the family.

 Neither Listing nor his wife seemed capable of managing the family finances :-

Listing borrowed frequently and heavily, sometimes from usurers; Pauline habitually abused credit, and again ended up in court with some regularity. They tended to live beyond their means, and on one occasion barely avoided bankruptcy.

 The near bankruptcy came around the time that Listing was publishing another remarkable contribution to topology. In 1858 he had discovered the properties of the Mobius band at almost the same time, and independently of, Mobius.
