That's why history exists and so we have family records and what they did and how they contributed to our history.
So on the maternal side we have the family sites: Miceli (Italian) and Araújo (Portuguese); on the paternal side we have the families: d'Avila (Portuguese) and Schaefer (German).
I Everaldo Miceli d'Avila, Brazilian, married, retired Business Administrator, researched websites that had family data, always looking for the source of good and safe information.
The first study we did was the Italian of the Miceli family, because we have access to more information on the internet, the second was from the surname Schaefer where we obtained information from a book edited by the relatives of Florianópolis who did the searches, the others ( d'Avila and Araujo) we didn't have a lot of information through the internet and the immigrants' museum, so we looked for family memories.
