An extensive analysis of the Maria family is presented. ... This is also confirmed by an analysis of the size distribution of the family, suggesting that about 10 objects in the 15--30 km size range have been probably lost. As a consequence, Maria's family can be seen as one of the most promising candidates as the source of the ``giant'' near--Earth asteroids 433 Eros and 1036 Ganymed. ... The obtained spectra are very similar and very much resemble the known spectra of Eros and Ganymed. ...
