Combining values using IF/Then search

Hello,

I am trying to combine two worksheets that have some similar data points but not all.
Example:
Sheet 1 has columns: Name, Age, Class
Sheet 2 has columns: Name, DOB

Twist: there may be >1 rows in Sheet 1 but only 1 row sheet 2 with the same Name (aka: multiple classes for same Name, but only 1 DOB entry)
I am looking for a way to combine all the values from sheet 1 and sheet 2 together so each row in sheet 1 has all the data on it.

Basically I'm looking for a way to parse through column A on sheet 2 and if there is a match, copy the value from Column B on sheet 2 to Column D on Sheet1.

Muchly appreciated!
