The history of the last name Isidro

The surname Isidro has its origins in Spain, where it first emerged in the medieval period. It is derived from the Spanish form of the Latin name Isidorus, which itself comes from the Greek words "isos" meaning "equal" and "doron" meaning "gift". This suggests the name may have originally referred to someone who was perceived as being of equal standing or possessing equal gifts.

Isidro is a patronymic surname, meaning it was originally formed by adding a prefix or suffix to the given name of an ancestor. In this case, the Spanish suffix "-o" was added to the name Isidoro to create the surname Isidro. This practice of deriving surnames from given names was common across medieval Europe.

One of the earliest recorded instances of the surname Isidro can be found in the Becerro de Behetrías, a 14th century census-like record of landowners and vassals in Castile. An entry from 1352 mentions one "Ferran Isidro" from the town of Villarmentero. Place names like this often provided the basis for surnames in that era.

The surname also has ties to Saint Isidore of Seville (c.560-636), a scholar and cleric who served as Archbishop of Seville and is regarded as the last of the Fathers of the Church. His influential writings and teachings likely popularized the name Isidoro/Isidro in Spain during his lifetime and the centuries after.

Other notable individuals with the surname Isidro include Juan del Isidro (1515-1594), a Spanish composer of sacred music during the Renaissance, and José Isidro Fabela Alfaro (1882-1964), a Mexican diplomat who represented his country at the League of Nations in the 1920s. Painter Francisco Isidro de Gárate (1804-1869) was a pioneer of Venezuelan romantic art in the 19th century.
