I installed JQLBooster Pack (from marketplace app store). This provides a JQL function called parentsOf() where you can pass any JQL query in the function call for parentsOf and you are supposed to get parent issues of all the items returned by the JQL sub-query. My query is something like this -
issue IN parentsOf("project = XX AND fixVersion = ABC AND type= Story"). However no results are returned when I know each of the story returned from the above query has a parent "New Feature" item
