Cold hardiness of Gertrude Jeckyl and Constance Spry

I was wondering what people's experience has been?
I've read:
-Constance Spry was tip hardy in zone 5 (Paul Barden or Henry Kuska)
What did people find in zone 4?
_ Gertrude Jeckyl dies to the ground but comes back (zone 3b? Or 4)
But how cane hardy is she? Zone five? Zone four?

I'm trying to plan for crosses with my F1 seedlings: some to gain more cold hardiness, while others to reinforce old rose look and Fragrance without losing too much of cold hardiness gained.
Thoughts?
Thanks!
Duane

4a Canadian “near” Rocky foothills.

My 2 Gertrude’s only survive in a sheltered spot. Usually cut canes down in spring to first new leaves - good year about 6” to 12”. Been flowering for 10-15 years. Other two planted in colder windy spots passed on long ago.

Constance did not make it - nor did any of the scores of Austins tried and not planted in a shelter spot, including the rugosa hybrids.
