Genealogy is more than just names and dates; it’s about understanding the places where our ancestors lived and the paths they traveled. Geographic Information Systems (GIS) mapping tools have become invaluable in genealogy, allowing researchers to visualize historical locations, migrations, and connections in a spatial context. This blog post will explore how both novice and experienced genealogists can use GIS mapping tools to enhance their research, providing insights, guidance, tips, and inspiration.

What is GIS and How Does it Benefit Genealogy?

GIS stands for Geographic Information Systems, a technology that allows users to create, analyze, and visualize spatial data. In genealogy, GIS can be used to:

• Visualize Ancestral Locations: Map out where ancestors lived, worked, and traveled.
• Analyze Migration Patterns: Understand the movement of families over time.
• Overlay Historical Maps: Compare old maps with current ones to locate ancestral properties and landmarks.
• Discover Geographic Context: Gain insights into the social, economic, and environmental factors that influenced ancestors’ lives.
