I'm not sure you can properly call it a "union" if there's only one state in it, but Delaware was the first state to ratify the US Constitution.
By the same logic, Pennsylvania (the second state to ratify the US constitution) wasn't really joining a union but forming one (with Delaware).
The third state to ratify the constitution (New Jersey) was therefore the first state that can unambigously be said to have joined an existing union of other states.
In practice, though, the Union is considered an ideal that existed as of the creation of the Constitution, and each state that ratified the constitution was joining that (hypothetical) union, so Delaware is really the first.
