Roosevelt Family Geneaology

Purpose of Graph

This very simple graph was used to help introduce students to graphing concepts. We started the class with a powerpoint presentation covering the nature of networks and graphs and basic coding for Cypher so that they would be prepared to work on a [Neo4j GraphGist](http://gist.neo4j.org/) on their own by the end of the hour class. Since everyone intuitively understands that family trees are derived from a set of relationships, the class was assigned to fork the graph below.

OUR DATASET

CREATE
//People

(elliott)-[:BEGAT]->(eleanor)

Encoding Exercise

Please consult the [Roosevelt family tree](https://en.wikipedia.org/wiki/Roosevelt_family) on Wikipedia and add additional elements to the family tree.

Querying with Cypher

Now let’s write some queries!

Name the People in the Graph

MATCH (person)-[:WAS_FROM]->(location)
RETURN person.name AS Name
