The starting point was Jacinto as follows:

This marriage for the parents appears to be close, but not an exact match:

Jose Dias Machado com Maria da Estrella;
Ele 25 anos, solteiro, campaneo, filho de Jacintho Machado and Maria Ricarda Dias;
ela 20 anos, solteira, domestica, filha de Francisco Mendes and Maria da Estrella, todos naturaes e moradores nesta freguesia;
However, the grandparents did not match for the name Joaquina de Jesus Dias married to the said Jacinto Machado. The closest match was this:
As you can see, this marriage works for Dias on one side and Mendes on the other. Maria Carlota seems way off, but there are no other names like this in Calhetas. I checked Fenais da Luz, but as yet not Rabo de Peixe for matches.
The baptisms for this couple, match for Jose Dias Machado and Maria da Estrella. So I believe an error was made and these are the correct ancestors for Jacinto, bap- 23-March-1890.
You should collect more baptisms to help verify the findings. Hope this helps.
