Organization and Degree of Familial
Relationships in Hispanic Cultures
Parentesco refers to the links or relationships
between members of a family. Understanding how these
are organized and measured is important in genealogical
These links are organized as lines (líneas)
and measured in degrees (grados). There are
three types of line,
- Blood lines (consanguidad)
- The links that exist between descendants of a
a common ancestor (e.g., grand parents,
parents, children, grand children, great grand
children, nephews, cousins, etc.).
- Affinity (afinidad)
- The links that, through marriage, each spouse
has with the other's blood relations (i.e.,
mother-in-law, daughter-in-law, sister-in-law,
etc.). In general, the blood relations of one
spouse does not acquire a legal relation with
the blood relations of the other spouse (e.g.,
are not legally related to each other).
- The links between the adoptee and the adoptive
parents and their blood relatives. This varies
from country to country.
