Executive summary

The name Marianne appears in Portuguese- and Brazilian-related contexts mainly as a given name borne by several public figures — notably Brazilian model and entrepreneur Marianne Fonseca (profiled in multiple outlets) and Brazilian-born artist Marianne Peretti (a French‑Brazilian) [1] [2]. Historical Portuguese female names more commonly appear as Maria (Queen Maria I) or variants; “Marianne” as a form is not highlighted in the supplied Portuguese-language month or naming resources [3] [4].

1. What the sources actually show about “Marianne” in Portuguese/Brazilian contexts

Contemporary Brazilian public figures named Marianne are documented in the sources: Marianne Fonseca is described as a Brazilian model turned beauty entrepreneur in feature coverage [1] [5] [6], and Marianne Peretti is recorded as a French‑Brazilian artist with a Brazilian father [2]. The presence of these individuals indicates that Marianne is used as a female given name in Brazil today, at least among notable persons [1] [2].

2. Historical Portuguese naming: Maria remains central

When the historical Portuguese record is considered, the prominent royal female form is Maria — exemplified by Queen Maria I of Portugal (baptized Maria Francisca Isabel…) whose reign and transatlantic role in Brazil are detailed in the historical account [3]. The sources emphasize Maria rather than Marianne in formal, historical Portuguese contexts [3].

3. Linguistic and cultural signals from the materials provided

Language-learning and month-name resources in the dataset do not address Marianne as a Portuguese name; they focus on standard Portuguese vocabulary (months, date formats) and broader Portuguese usage without listing Marianne among examples [4] [7] [8]. That absence suggests Marianne is not presented as a canonical Portuguese month/name example in these teaching resources [4] [7] [8].

4. Two competing readings: imported name vs. native form

The sources imply two plausible interpretations. One: Marianne functions as an imported or cosmopolitan personal name that appears in Brazil’s multicultural naming landscape — supported by profiles of contemporary figures like Fonseca and Peretti [1] [2]. Two: traditional Portuguese usage historically favors Maria and other Iberian forms; Marianne is not surfaced in historical or language-reference materials provided here [3] [4]. The reporting suggests Marianne exists in Brazil chiefly through individual usage rather than as a historically entrenched Portuguese variant [1] [2] [3].

5. Notable examples and what they imply about social usage

Marianne Fonseca’s press profiles present her as a Brazilian-born public figure and entrepreneur, indicating the name’s visibility in contemporary Brazilian media and global fashion press [1] [5] [6]. Marianne Peretti’s biography documents a bicultural lineage (French mother, Brazilian father), showing how transnational families bring names like Marianne into Brazilian cultural spaces [2]. These concrete examples explain why the name appears in coverage, even if it’s not standard in traditional Portuguese naming references [1] [2].

6. Limits of the available reporting and what is not said

Available sources do not provide statistical data on the frequency of “Marianne” in Portugal or Brazil, nor do they explain whether Marianne is considered a Portuguese-language variant of Maria or a distinct imported form; those specifics are not found in current reporting (not found in current reporting). The language resources and historical overview supplied do not treat Marianne as a canonical Portuguese form, leaving a gap on formal etymology or population-level usage [3] [4] [7].

7. Takeaway for readers seeking a quick answer

If your question is “Is Marianne a Portuguese/Brazilian woman’s name?” the documented answer in these sources is: yes—there are Brazilian women who bear the name (Marianne Fonseca, Marianne Peretti) and they appear in mainstream coverage [1] [2]. If the question is whether Marianne is an historically traditional Portuguese equivalent of Maria, the evidence provided shows Maria is the historically central form and Marianne is not emphasized in the historical or language-reference materials here [3] [4].

If you want deeper proof about popularity, origins, or whether Marianne is commonly used across Portugal versus Brazil, available sources do not mention naming-frequency data or formal etymological treatment for Marianne in Portuguese.
