The first Abreus came to Madeira IN 1497 when Beatris Abreu received a grant of land from the King at Arco da Calheta. The best book for information is in Portuguese entitled Register of theGenealogies of Families who lived in Madeira. By Luiz Peter Clode published in 1950 by Tipografia Comercial in Funchal. I am an Abreu and will be going to Madeira for one month in December. The best records of family births, deaths, and marriages are in the archives in Funchal but you can see them by going to the Family Center of any Morman Church and ordering a copy of the records to be viewed at the center.
