The highest incidence in Mexico, with 2,913 records, followed by France with 2,565 and Spain with 2,410, indicates that its roots are probably linked to the Iberian Peninsula and, subsequently, to migrations to America.

Etymology and Meaning of Castan
The surname Castan appears to have a root that could be linked to terms related to nature or place names, although its structure also suggests possible connections with linguistic roots from Spanish or French. The form Castan does not have typical patronymic suffixes in Spanish, such as -ez, or prefixes that indicate lineage, so it is likely a toponymic or descriptive surname. The root Castan could derive from the noun castaña, which in Spanish means 'fruit of the chestnut tree', or from the term castaño, which also refers to a color or a tree. In this context, the surname could have originally been a nickname or descriptor for someone who lived near chestnut trees or who had some relationship with chestnut trees, which would classify it as a toponymic or descriptive surname.
From a linguistic perspective, the word casta in Latin is castanea, which means 'chestnut', and which was adopted in the Romance languages to designate both the tree and the fruit. The form Castan could be a regional variant or abbreviated form of Castano or Castaneda, surnames that also have roots in toponymy related to chestnut trees. The absence of patronymic suffixes in the simple form suggests that the surname would not be patronymic, but rather toponymic or descriptive.
As for its classification, Castan would probably be considered a toponymic surname, given that it could be associated with places where chestnut trees abound or with rural areas with the presence of these trees. It could also be descriptive in nature, referring to physical characteristics or a natural environment. The possible relationship with terms that denote color or physical characteristics also opens the possibility that in some cases it has a descriptive origin, although this would be less frequent.
In summary, the etymology of Castan seems to be linked to the word chestnut, with roots in the Latin castanea, and its meaning would be related to the tree, the fruit or the color chestnut. The structure of the surname and its geographical distribution support the hypothesis of a toponymic or descriptive origin in regions where the presence of chestnut trees was significant in rural and agricultural history.
History and Expansion of the Surname
The analysis of the current distribution of the surname Castan suggests that its most probable origin is in the Iberian Peninsula, specifically in regions of Spain where the presence of chestnut trees was relevant in agricultural and rural history. The significant presence in Spain, together with the high incidence in Mexico, indicates that the surname may have been formed in the Middle Ages or in later times, in areas where chestnut trees were abundant and were part of the natural and economic landscape.
During the Middle Ages, in the Iberian Peninsula, toponymic surnames frequently emerged to identify people in relation to their place of residence or with characteristic elements of the environment. In this context, Castan could have been a surname that identified those who lived near chestnut groves or in rural areas.with abundance of chestnut trees. The expansion towards America, particularly towards Mexico and Argentina, probably occurred in the 16th and 17th centuries, within the framework of Spanish and Portuguese colonization, when many Spanish surnames settled in the American colonies.
The presence in countries such as France and Germany may be related to European migratory movements in the 19th and 20th centuries, in which families of Spanish or French origin took the surname with them. The dispersion in Anglo-Saxon countries, such as the United States and Australia, can also be explained by more recent migrations, in search of better economic opportunities or for political reasons.
The current distribution pattern reflects an expansion process that combines colonization, internal migration and international migrations. The high incidence in Latin American countries, especially in Mexico and Argentina, reinforces the hypothesis of an origin in the Iberian Peninsula, from where the surname spread through colonial and migratory routes.
In short, the history of the surname Castan seems to be marked by its toponymic or descriptive character, with an origin in rural regions of the Iberian Peninsula, and an expansion that was favored by the colonial and migratory movements of subsequent centuries.
