My Great-great-grandmother was Matilda Mendonca originally from Madeira, Portugal. She was married to (John?) Manuel Franco also from Madeira. They lived in Plaisance, British Guyana. They had 6 children: John, Manuel, Louis, Antonio, Joseph and Deolinda Maria (my Great-grandmother) born Sep 30 1882. I'm trying to find more on Matilda/Manuel.
