Why a hash? If it only contains names, then why not

names = ["Admiral Ackbar", "Bail Organa"]

Or so you want a hash with multiple values for one key:
{"name"=>["Admiral Ackbar","Bail Organa"]}

myhash = Hash.new { |h,k| h[k] = [] }

myhash["name"] << "Admiral Ackbar"
myhash["name"] << "Bail Organa"

Otherwise, as others have suggested, an array of hashes:

[{"name"=>"Admiral Ackbar","age"=>30},
 {"name"=>"Bail Organa","age"=>65}]

Or choose some attribute as a key, like id

{ 1 => {"name"=>"Admiral Ackbar","age"=>30},
  2 => {"name"=>"Bail Organa","age"=>65}}
