Is a great-grandfather a legacy at Penn?

Just in the junior year so not sure what the application is like. Does it prompt for relatives or only parents, only parents or grandparents, etc.? I tried a quick web search and it looked like maybe just parents and grandparents.

DD20’s great grandfather is a Penn alum.

I called Penn recently and was told that only parents and grandparents count for legacy.

“Only” really being a misnomer. Penn is being generous by considering grandparents; some colleges only consider parents. And you gotta draw the line somewhere.

Thanks!
