Name-on-name bonus is an advanced rule (see Name-on-Name Bonus in the rulebook). When this rule is in effect, an enhancement card with a person’s name in the title is worth double its abilities (*/*) when played on a character card that has the same specific person’s name in the title. Play name-on-name bonus as “person's-name-on-same-person” bonus, because there are examples in the Bible where the same person has multiple names that are reflected in Redemption®. Name-onname bonus does not affect nor is it affected by the special abilities on cards. Characters must be unique; generic characters cannot be used for name-on-name bonus.
While The Generous Givers are people who were Giving Generously, this is not The Generous Givers' Giving and thus I would not see it as name-on-name.
Interesting thought, but would not work as I see it.
