I am writting from France. I am French and was surfing on the Genealogy web site and found your mail. You should try on the Genealogy forum of Malaysia, there is a lot of Pereira. They seem to be related to Singapore and Malacca. I am also searching for Pereira, my great grand father. I don't have his first name but i know he had my grand ma Emily born in Laos, who married an american captain named Reynolds.
If you have any information, it would be greatfull. Sincerely Elisabeth Lazaroo
