COURSE BREAKDOWN

Each lesson is a project where you build up queries to produce a useful report from the data in your family tree.

Lesson 0: Convert Your Family Tree Into A SQL Database

You should already have a family tree (online or in desktop software).

We’ll walk you through exporting the tree to a GEDCOM file and creating a SQL database on your Windows or Mac computer.

Lesson 1: Creating The Person List

Build a detailed SQL report of every person in your family tree, complete with birth and death details alongside their parents’ names.

If you’re a SQL beginner, you’ll learn how create and combine subqueries to make a single list.

Lesson 2: Creating a Surname Frequency Report

Generate a frequency report of all surnames in your family tree, giving you insights into the most prominent family lines.

If you’re a SQL beginner, you’ll learn how to group data to produce summary insights.

Lesson 3: Parsing Address Details into Towns, States, and Countries

Learn how to parse birthplaces and deathplaces into manageable pieces for further analysis.

By the end, you’ll have a cleaner, more organized set of data.

Lesson 4: Creating Frequency Reports for Addresses

Building on what you learned in Lesson 4, this lesson will teach you how to create frequency reports for the various addresses in your family tree.

By the end, you’ll be able to identify key locations in your family’s history, adding depth to your genealogy research.

Lesson 5: Creating the “At This Place” Report

Learn how to create a report that lists all family tree events at a specific location.

You’ll be able to pull together these events into a cohesive report, giving you a clear view of your family’s activities in particular towns, states, or countries.

Lesson 6: Creating the “On This Date” Report

Create a report that lists all family tree events on a specific date.

Compile these events into a detailed report that lets you focus on significant days in your family’s history.

Lesson 7: Identifying Duplicate Entries in Your Family Tree

Learn techniques to spot and handle duplicate individuals that are messing up your tree. This helps keep your genealogy data accurate and clean.

Lesson 8: Identifying Age Issues in Your Family Tree

Discover how to check for age discrepancies.

For example, find individuals with lifespans beyond typical life expectancy or women having children outside typical child-bearing ages.

Lesson 9: Identifying Missing Details in Your Family Tree

Use SQL to detect and highlight missing details in your tree.

For example, run reports to show all people without a death location or married women without a known maiden name.

Lesson 10: Extracting Ancestral Lines with Recursive Queries

Recursive querying is one of the more advanced SQL topics. This lesson will show how to build recursive queries to show ancestral lines.

Lesson 11: Your Ancestor Gap Report

Analyze your data to pinpoint which ancestral lines have gaps and missing ancestors.

This shows you where to direct and focus your family research.
