International Genealogical Index batch numbers can make plowing through the piles of Mexican records muy simple.
A batch search lets you jump from the record for one ancestor to other record extracts entered at the same time from the same parish or town. Once you’ve done a successful IGI search—say, you’ve found your ancestor Martin Hernandes, christened June 15, 1834, in Huejutla De Reyes, Hidalgo—just click on the batch number (C612612) in the lower left corner of the screen. That automatically brings up a new IGI search on the batch number. Now you can fine-tune your criteria or just click Search to see all individuals from the batch. (If you’ve found an ancestor at <pilot.familysearch.org
>, just copy the batch number and paste it into an IGI search.)
