Some question about parentage, see References.

Also about breeder, per this email: My aunt tells me that my grandfather (John Swann) bred this rose, I think, sometime before the Second World War when he was employed at the Royal Nurseries in Waltham Cross Hertfordshire England and that we had this rose growing in the garden of the family house at this time and I can remember seeing a rose of this description when I lived there. Is there any way of telling for sure whether this rose was established by my grandfather during the reign of King George V? This was the period when he worked at the Royal Nurseries.
