passage: Princess Marie Louise of Bourbon-Parma
In 1892, her father arranged her marriage to the then reigning Prince of Bulgaria, Ferdinand of Saxe-Coburg and Gotha. The negotiations were conducted between Duke Robert and Ferdinand's mother, Princess Clémentine of Orléans. The engagement was celebrated at the Castle of Schwartzau, the residence of the Bourbon-Parma family in Austria. Marie-Louise and Ferdinand had never met prior to that day. Princess Clémentine, who was present on that occasion, described her future daughter-in-law in a letter to Queen Victoria as "Unhappily not very pretty, it is the only thing which is lacking, since she is charming, good, very witty, intelligent and very likable". The wedding took place on 20 April 1893 at the Villa Pianore in Lucca, Italy, the residence of Duke Roberto in Italy. Marie Louise was twenty three, nine years younger than Ferdinand. The couple wasted no time producing an heir, with son Boris born nine months and ten days later.
