Origin of the Surname McDonnough
The surname McDonnough presents a geographical distribution that, according to available data, shows a significant presence in the United States with 305 incidents, followed by Jamaica with 166, and a minor presence in countries such as England, Barbados, the United Arab Emirates and Australia. The primary concentration in the United States and Jamaica, along with the presence in English-speaking countries, suggests that the surname has roots in English-speaking communities or in immigrants who brought their heritage to these regions. The notable incidence in the United States, in particular, may be related to migratory processes of European origin, specifically British or Irish roots, who settled on the American continent during the 18th and 19th centuries.

The surname McDonnough is clearly of Anglo-Saxon or Celtic origin, specifically Gaelic roots, given the prefix "Mc-", which in Scottish and Irish surname tradition means "son of".

The structure of the surname, with the prefix "Mc-", indicates that it is a patronymic, that is, it originally designated "son of Donnough" or "son of Donnach". The ending "-ough" in Anglo-Saxon or Anglo-Irish transliteration may reflect a phonetic adaptation of the Gaelic root, which in its original form could have been "Donnach" or "Donn". The presence of the prefix "Mc-" and the phonetic structure suggest that the surname belongs to the category of patronymics typical of the Gaelic communities of Ireland and Scotland, where these surnames were formed around the given names of prominent ancestors.

History and Expansion of the Surname

The history of these regions, marked by the presence of clans and families with surnames that reflected specific lineages, favored the formation and transmission of these surnames through generations.
The dispersion of the surname outside the Celtic regions may be linked to the migratory and colonial movements of the 17th to 19th centuries. The emigration of Irish and Scots to North America, in search of better economic conditions and escape from political and religious conflicts, was a key factor in the expansion of the surname. In particular, during the 19th century, the Great Famine in Ireland caused a wave of migrants to the United States, Canada and other English-speaking countries, taking their surnames with them.traditional.
The significant presence in the United States, with more than 300 incidents, may reflect the integration of families of Irish or Scottish origin in the country's history, participating in colonization, mining, agriculture and other economic sectors. The presence in Jamaica, with 166 incidents, can be explained by the migration of British settlers and the influence of English-speaking communities in the Caribbean colonies during the colonial era. The expansion towards countries such as Australia and the United Kingdom can also be attributed to the emigration of these communities in search of opportunities in the territories of the British Empire.
In summary, the current distribution of the surname McDonnough reflects a typical pattern of surnames of Celtic origin that, after their formation in Ireland or Scotland, expanded through colonial migrations and migratory movements in the 19th and 20th centuries. The presence in English-speaking countries and in immigrant communities confirms its roots in Celtic cultures and its subsequent diffusion in the Anglo-Saxon world.
