I am doing research into my early Ferreira relatives, and I think I have a good base up to my x3 great grandfather Antonio Ferreira (born in 1858 (in Ginetes - Ponta Delgado - Sao Miguel). I believe he is my x3 great grandfather, I know a lot of early records sometimes combine one or more people together. His son, Jose 'Joseph' Ferreira (1874-1937) immigrated to the US with his wife Theresa Rapoza (1874-1923) who had a son named Manuel (1907-1961). His son, Roger is my grandfather. My father and grandfather have been dead for over 20 years so getting any information about his side of the family can be tricky from 1st person sources. I've tried using
