  Marx and von Westphalen had seven children together, but partly owing to the poor conditions in which they lived whilst in London, only three survived to adulthood. Their children were: Jenny Caroline (m. Longuet; 1844–1883); Jenny Laura (m. Lafargue; 1845–1911); Edgar (1847–1855); Henry Edward Guy ("Guido"; 1849–1850); Jenny Eveline Frances ("Franziska"; 1851–1852); Jenny Julia Eleanor (1855–1898) and one more who died before being named (July 1857). According to his son-in-law, Paul Lafargue, Marx was a loving father. In 1962, there were allegations that Marx fathered a son, Freddy, out of wedlock by his housekeeper, Helene Demuth, but the claim is disputed for lack of documented evidence.
  
  Helene Demuth was also largely entrusted as a confidante. In her obituary, penned by Friedrich Engels, her role is revealed as: "Marx took counsel of Helena Demuth, not only in difficult and intricate party matters, but even in respect of his economical writings".
  
  Marx frequently used pseudonyms, often when renting a house or flat, apparently to make it harder for the authorities to track him down. While in Paris, he used that of "Monsieur Ramboz", whilst in London, he signed off his letters as "A. Williams". His friends referred to him as "Moor", owing to his dark complexion and black curly hair, while he encouraged his children to call him "Old Nick" and "Charley". He also bestowed nicknames and pseudonyms on his friends and family, referring to Friedrich Engels as "General", his housekeeper Helene as "Lenchen" or "Nym", while one of his daughters, Jennychen, was referred to as "Qui Qui, Emperor of China " and another, Laura, was known as " Kakadou " or "the Hottentot ".
