Our great grandfather Wong Teng Mo Was born in Macau to a british mother and chinese father. We estimated his birth somewhere around 1880 - 1890. He had one brother, which we know not to much about Wong Teng Feng. His wife Salome Madrazo is of portuguese and spanish descent. He came to Zamboanga, philippines around 1908 - 1910. He then changed his name to Santiago Wong Rodriguez. A lot of the paper work we had was burned in the 40's during the war and there is only one remaining relative that is alive that knows information.
So I just want to know:
1) What would be the best way to find any info on his mother and father?
2) Would any offices in the philippines carry information on his parents?
3) From what part of portugal did most people that inhabited Macau come from? Lisbon?
4) Is there any specific region of England that immigrated to Macau?
Thanks in advance!
