BERTEMATI: Noble lineage of Italian origin, which appears as Vertemati, Vertemate, Bertematti, Bertemati or Bertematy.

According to Gofredo di Crollalanza in his "Stórico-blasónico Dizionario delle Famiglie Nobili e Notabili Italiane Estinte e Fiorenti" it is a noble and ancient family originally from Milan, which occupied in the eleventh century the castle Vertemate between Milan and Como. A branch was established in Piuro in County Chiavenna. Nicolò Vertemate was secretary of Emperor Charles VI in the year 1731.. Baldassarre Vertemati or Bertemati was created Baron Empire in the year 1795, with branch defunct. From Milan the family moved to Spain, where the name appears more plentifully as Bertemati. They took root in the city of Jerez de la Frontera, where one finds the Palace of the Marqués de Bertemati, a baroque building located in the Plaza del Arroyo, built in 1758. With an impressive Rennaissance facade, some of its highlights are balconies of finely-wrought iron work. The last Marquis of Bertematti, Monsignor Bertemati, yielded the house to the Sisters of Immaculate Mary in 1942. A restoration began in 2002 and in 2005 the palace became the new House of the Church of the Asidonia-Jerez Diocese of Southern Spain.

The Queen Regent Maria Cristina of Austria, on behalf of D. Alfonso XIII, May 13, 1888, granted the title of Marquis of Bertemati to Don Jose de Bertemati and Troncoso, of which there are precedents in the General Archive of the Ministry of Justice. Also awarded the title of Earl of Bayonne, August 4, 1875, Don Manuel Mass and Bertemati, of which there are precedents in the General Archive of the Ministry of Justice and subsequently, the October 21, 1889, was created Marquess of Mass with Greatness of Spain. This name is found in Cuba and Mexico. It has been found that populations in places where they are located Havana (Cuba), with data from the year 1788 and the Federal District of Mexico with data from the year 1810. Chronicler and Dean King of Arms, Don Vincent Chain and Vincent, in his "Code of Blasones of the Hispanic Community", writes of Bertemati the following:

WEAPONS: a lion rampant on silver, having a gules border on a sable field.

FEATURES: glazes symbolize: SILVER: Purity, Integrity, Obedience, Firmness, Eloquence and maturity. GULES: Fortress, Victoria, Osadía, Highness and Ardid. SABLE: Prudence, Sadness, Rigor, Honesty and Obedience. The Wolf is a symbol of a Heart Constant that suffers the calamities of war and siege with generous spirit, but in time for the fight on open field, fights fiercely, without giving his enemy quarter.
