Hello June, I recently returned from China on business and do not remember if I responded to your inquiry. Tell me where you are located and I can then refer you to the closest Macanese Cultural Club that may have a book by Jeorge Flores which documents Portugues families that immigrated to Macau and their decendants. I was able to trace my ancestry back to 1750. Castilho is a name I recognize and through many intermarrages, we may be related.
