Jack were roses siblings "delilah" and "turbo" ever bred? If so how did their offspring do? And were these the only siblings of rose?

Also the breeding of poncho x rosey, and the breeding of thunder to rosey what were the overall similarities between these two breedings (seeing how the are pretty much three quarter siblings)

And finally would the two best overall producers of these two breedings be considered "Chase", and "Razor" like peds indicates?
