The surname of Busuá may have survived as a surname of African origin due to its similarity to a French stylized name. The addition of the accent at the end of the name may indicate a French/Haitian influence allowing it to survive.

In Las Charcas there are two main branches of descendants with the surname Busuá. The branch that I descend from comes from Francisca Busuá who married Manuel Rodríguez having two sons, Serafín and Zenón Rodríguez Busuá. Zenón married Felipa Busuá connecting this branch again to the family. The paternal lineage of the Rodríguez family is African with the haplogroup E-M4451 (E-CTS9106 > E-FTB90151).

The primary branch of the family descends from Florimon Busuá, a native of Santiago and son of Juan and Rosalía. He was first married to María Eugenia Hernán (also used López) and had three children with her, Baltazar de los Reyes, Teresa de Jesús, and Miguel Busuá Germán. Later on, Florimon remarried to Isabel Fabián Núñez, who went by Isabel Mata in his burial record. It appears they did not have any children and she remarried to Pedro María Rodríguez Flores the same years she died in 1904.

Miguel Busuá Germán would marry a relative of the Busuá family, María Felicita Rodríguez Fabián. Her father Florencio Rodríguez Busuá was the son of Zenón Rodríguez and Felipa Busuá. Zenón was the son of Manuel Rodríguez, likely the same Manuel Rodríguez was was married to Francisca Busuá. Unfortunately, the couple did not receive a marital dispensation so we do not know for sure how the unconnected branches of the family are related.

The following is complete speculation: Miguel was likely from the same generation of Felicita's father, Florencio Rodríguez. The father of Miguel, Florimon Busuá, was in his sixties when Miguel was born. Florencio's father was in his fifties when Felicita was born. Felipa and Florimon Busuá were likley from the same generation and may have been siblings. Francisca Busuá, the wife of Manuel Rodríguez and paternal grandmother of Florencio, may have been the aunt of Felipa and Florimon.

A clue to a possible Haitian connection is in the name Florimon. A Haitian general who resided in San Francisco de Macorís had the same name.

The family would eventually change their surname from Busuá to Germán through the lineage of Baltazar de los Reyes Busuá Eman. As the only individual who's lineage carried the surname, after this change the surname became extinct in the Dominican Republic.
