A loooong time ago, when I was in business school, we were taught that it takes ten positive customer encounters to overcome one bad one. The point then was to get the customer to have the ten good experiences before the bad one. Geese are kind of the same way, except they have a really hard time overcoming the one bad experience. And they tend to transfer the bad experience to the whole set of circumstances.
Your goose saw the hoe as a threat, and she immediately included your daughter to be part of that threat - better safe than sorry. You may be able to reverse the reaction, but it takes a lot of time and patience. Especially now that the goose has been reinforcing her belief that your daughter is a threat several times.
If you keep your daughter away from the geese for a couple of days, it gives the goose a chance to get back to "DEFCON 5". Then you could reintroduce them, approaching calmly and loudly (not sneaking quietly, they hate that), pausing every time the goose even hints at reacting, and respecting her definition of a safety zone.
It should work, but with a mother goose there's always a high risk of something else setting her off.
