Portuguese 23andme results!

[Nico Nobrix]

You are more than 2% SSA.

Sub-Saharan 3.00
Northeast_African 2.56

Yes, 3%. Portuguese on GEDmatch have 1% so I deviate from the average mainlander by 2%, which is why 1% is embedded in European on 23 and me

I figured what influenced my dark features was a general old iberian phenotype, before Iberians mixed with Celts/Germanics. Since I dont have African features.

You have to remember that all native Iberians have North African DNA, alot of it comes from thousands of years BC, they found Skeletons from 2,000BC with 100% North African DNA. So when you calculate 4-5% African. Some of that goes to North African influence. But that 3% SSA, almost all of it I am guessing is from the last 400 years

Any history of reverse migration from Brazil to Portugal?

Yes, there was quite a bit of it in the late 19th century and early 20th century with many Portuguese who had emigrated and made a fortune returning to Portugal to build what at the time were considered tacky nouveau-riche style mansions, with many dotting small towns throughout Northern Portugal. There is a thread below. It is estimated that most of the emigration from Portugal to Brazil during the 1880 to 1920 period remained male and around one-third of the emigrants returned to Portugal, with Portuguese immigrants to Brazil having higher of exogamy in Brazil than other European immigrant groups.

Anecdotally, in my parents home small town in Central Portugal I found the marriage record from 1816 of a woman listed as having been born and baptised in Rio de Janeiro. This woman died in 1843, and judging by the marriage records the age of her children was presumably born around 1790. The priest lists her mother as being from Minas Gerais and she took on the last name "Mineira" which was passed down to some of her descendants and still exists in this town.

The link below shows some of the houses built by returning emigrants called "Casas de Brasileiros".

Its clear OP is related to some Brazilian ancestor.
