Resources and Tools

Methodological guides, utilities, and the documentary corpus of the research.

To better understand how a family tree is structured and to facilitate your own research, we have compiled these classic methodologies, useful tools, and the complete bibliography of the sources used in this project.

1. Family Researcher's Kit

To transform the visitor into an active historian, we have designed this standardized documentary corpus. These methodological tools will allow you to collect, validate, and preserve family memory with professional rigor.

2. Genealogical Methodology

Explanation of the international numbering systems used in the organization of this tree.

Sosa-Stradonitz System

The world standard for numbering ancestors. Number 1 is assigned to the base person. The father's number is always double, and the mother's is double plus one. It allows knowing the exact relationship just by looking at the number.

Descendant System

Ideal for listing all the descendants of a founding ancestor. A number is assigned to each generation and a digit is added for each child according to their birth order (e.g., 1.2.1).

Soundex System

Fundamental phonetic algorithm for finding poorly recorded immigrant records. It converts surnames that sound the same (e.g., Pozzo, Pozo, Poso) into the same master code to make them easier to find in the archives.

3. Researcher's Tools

Historical Age Calculator

Calculate the exact age of an ancestor on a specific date (e.g., age at marriage).
