The Surname Ledesma. From Salamanca to Guanajuato to Los Angeles. When you search the online White Pages for the Los Angeles, California, area, you will find that there are 98 Ledesma's living in the L.A. area. This surname Ã´Ã§Ã´ while not very common in the overall population Ã´Ã§Ã´ is prevalent in several parts of both Mexico and the United States (especially Texas and California). Members of my own family are descended from the Ledesma's who lived in Guanajuato for more than three centuries.
