FYI: IGI Searches by John Schmal
I wrote to John Schmal and he gave me permission to send this to the group. joseph ======================================= Dear Associates and Fellow Members:
The following notes are rules of thumb for International Genealogical
Index (IGI) searches in Mexico. (© 2000 by John P. Schmal, JohnnyPJ@...).
The IGI is a dynamic database that can be of tremendous help in locating Mexican
ancestors between 1700 and 1880. It has a filter, so that you can limit
your search to particular states.
1. Don't be confused by spelling. The IGI groups together similar
sounding surnames through soundexing. Spelling is the least reliable
indicator in Mexican genealogy. A surname that is spelled one way in
1800 may be spelled differently in 1850. Robalcaba may be spelled
several ways: Rubalcaba, Rubalcava, Robalacaba, Robalcava.
2. Always consider how close your locality is to the nearest state
boundary. People moved around. They may be in Sinaloa in one generation
and in nearby Sonora in the next generation.
3. Always consider using Jose and Maria in front of given names, when
searching for baptism and marriage records, especially if you are unable
to locate your ancestors under their assumed given names. Thus, if you
are looking for Matias Calvillo, born in 1850, also try searching for
Jose (Matias) Calvillo.
4. When putting in a date, make it about five to ten years before the
assumed date of baptism or marriage.
5. Always remember that people are not always born where you thought
they were. They might be born twenty miles away in another town. Don't
rule out anyone just because they aren't listed in the exact town where
you expected to find them. Sometimes we are constrained by the knowledge
we have because it leads us to reject new information (that may be correct).
