My Greatgrandfather Manuel B. da Silva born 1870 on the Eastern part of Sao Miguel (Lagao/Provacao....) married Maria Madeira (though I have info showing it spelled Medeiros) born between 1873 & 1880, also in the same area. Their children born in the Azores are: Maria about 1892, Irmelinda 1895, Maria Anjos 1897 (Anjos changed to de Sourle on the 1910 US Census), Manuel 1902, Francisco 1903. They emigrated to the US in 1906 and 'Americanized' their last name by dropping the da. They had three more children in Hawaii. I am trying to find Manuel & Maria's date of birth, marriage, and any previous ancestors. Any help out there?
