Elísio Sevier Wallace and his wife Mary came to Brazil in 1867 or 1868 and probably had their children here in Brazil. Wallace came to own some sites, helped open roads in the region and returned to the United States in 1912 to buy equipment and machinery. All the daughters of the Wallace couple married Brazilians.

Elísio Wallace lived in Santarém until his death in 1912, at the age of 73 and left descendants in Belém, Manaus and Santarém itself (in the photo, on the right, Mr. Wallace and right behind him, his grandson).
