My name is Carlos A. Heuser. I live in Porto Alegre, in the state of Rio Grande do Sul, the southmost state in Brazil. I'm a retired Computer Science professor at the Universidade Federal do Rio Grande do Sul, in Porto Alegre. Appart from being a genealogist I am also a passionate photographer.

The basis of this site is TNG, a software written by Darrin Lythgoe in PHP that manages a MySQL database that contains the family trees.

I received the Benckes and Diefenthaelers family trees as MS Word files containing descendancy reports in textual format each one in a different format. In order to transform them into GEDCOM I wrote two PERL scripts.
