Keeping Data Together While Adding Information?

I have two excel sheets in the same workbook. I've linked column B2 in Sheet1 with column A1 in Sheet2. It works great!

The only problem is that when I add a row in Sheet1, it appears in Sheet2, but the rest of the data on that sheet doesn't move alongside the rest of the rows. So if Sheet2 looks like this:

Abby 16
Amy 15
Jenna 14

And I add in another name in Sheet1, lets say Ben, then Sheet2 will look like this.

Abby 16
Amy 15
Ben 14
Jenna

when I want all my data to stick together.
