black Americans with roots in Louisiana can see trace Filipino ancestry while Black Americans with roots in Virginia can see trace Malagasy ancestry. Malagasy ancestry is often coded as Indonesian + Austronesian in 23andMe since the Austronesian ancestors of the Malagasy people traveled west from Borneo, Java, and Sumatra.
Southern Philippines likely denotes a very distant Bisayan ancestor as Tagalog and Bisayan people, alike, were brought on ships as part of the Manila Galleon and to help with some colonial projects, however, the Filipinos who eventually settled St. Malo in Louisiana escaped these conditions of what was essentially forced labor at the hands of the Spanish.
The minor filipino heritage of most African Americans in Louisiana comes from Virginia. One of the reason why "Jefferson" is a common last name amongst black people was due to selling Virginians to NOLA and above.
New Jerseyans and New Yorker of black colonial descent can get as high as 6% Asian and they were sold down in Louisiana as well.
Manilamen are very specific in Louisiana, at this point you'd know you had a Filipino ancestor. They were legally white and very vocal about their identities.
The group also was not too keen to have children with black women; the records showed they married Isleno/Irish/French women, mixed daughters could only marry other Manilamen or occasionally Islenos men the first couple generations. They also lived in only a particular stretch of Louisiana where if a woman married a black man the whole community would be in jeopardy.
