groovy - Pulling a field from a list based on second list

I have the following lists:

list1 = [["value1":"name1", "value2":"check1"], ["value1":"name2", "value2":" check2"],  
["value1":"name3", "value2":" check3"]]  
list2 = ['name1', 'name2']

I would like to pull the list of all the "value2" for name1 and name2. as:

[check1, check2]
