simple-gedcom 1.0.8

A Python module for reading and extracting data from GEDCOM files.

Simple GEDCOM Parser

A simplified Python library for extracting genealogy data from GEDCOM files:

1. Extract basic person data - Get a list of people with vital information
2. Extract sources - Get lists of documentary sources
3. Extract pedigree - Get direct ancestors

Features

• Parse GEDCOM 5.5 files
• Extract person data: names, birth/death dates and places, parents
• Flexible person data options: basic, extended (suffix, gender, status), or with marriages
• Extract marriage data: spouses, marriage dates, and family IDs
• Extract source citations linked to individuals
• Extract pedigree
• Simple, clean API designed for data analysis and writing to csv files

Quick Start

# Read a GEDCOM file and write lists to CSV files
from simple_gedcom import load_gedcom

gedcom = load_gedcom('data/tree.ged')

gedcom.save_person_list_to_csv()
gedcom.save_person_list_to_csv(extended=True)
gedcom.save_person_list_to_csv(marriages=True)
gedcom.save_person_list_to_csv(extended=True, marriages=True)

gedcom.save_pedigree_to_csv()

gedcom.save_source_list_to_csv()

gedcom.save_person_source_list_to_csv()

# pedigree analytics
pedigree = gedcom.get_pedigree()

gedcom.show_generation_counts(pedigree) 

gedcom.show_pedigree_duplicates(pedigree) 

# Use pandas to display lists
import pandas as pd

# Basic person list
person_list = gedcom.get_person_list()

# With extended fields (suffix, gender, status)
person_list = gedcom.get_person_list(extended=True)

# With marriage columns (spouse names, marriage dates, family IDs)
person_list = gedcom.get_person_list(marriages=True)

# Combined
person_list = gedcom.get_person_list(extended=True, marriages=True)

df_person_list = pd.DataFrame(person_list)
print(df_person_list.head())

sources = gedcom.get_source_list()
df_sources = pd.DataFrame(sources)
print(df_sources.head()) 

person_sources = gedcom.get_person_source_list()
df_person_sources = pd.DataFrame(person_sources)
print(df_person_sources.head())

pedigree = gedcom.get_pedigree()
df_pedigree = pd.DataFrame(pedigree)
print(df_pedigree.head())

# Search by name
found = gedcom.find_persons_by_name(first_name="Theodore")
df_found = pd.DataFrame(found)
print(df_found.head())

# Show the pedigree for a specific person (by ID)
pedigree = gedcom.get_pedigree("@I162694122750@")
df_pedigree = pd.DataFrame(pedigree)
print(df_pedigree.head())
