i'm looking for information on anyone with the last name serrao from madeira, portugal who immigrated to africa. my grandmother's brother, abel pereira serrao, supposedly immigrated to transvaal, south africa to work in the gold mines. unsure when, but probably sometime around 1910. there may have been another brother named either antonio (antone?) pereira serrao or manuel pereira serrao who immigrated to either angola, transvaal or mozambique. i would appreciate any information that i get. thank you
