Compare two gedcoms for missing and differing data, producing a CSV which should be readable by any spreadsheet.

I use this to compare my Gedcoms on FindMyPast and Ancestry. It could also be of use to compare Gedcoms with those of a family member.

• gedcom - a general purpose utility for Gedcom files
• ged2site - create a website from a Gedcom file

This script compares individuals across GEDCOM files and reports those who share both the same birth and death dates.

• Uses the Gedcom CPAN module for parsing
• Normalizes birth and death dates to avoid mismatches due to formatting
• Skips invalid or incomplete individuals gracefully
• Compares data across multiple GEDCOM files
• Identifies potential duplicate individuals by exact birth/death date matches

This module is provided as-is without any warranty.
