Beautiful blooms, Sue. The first two of the pink Montana could be any number of cultivars, but my guess would be montana Elizabeth. It is popular here in the U.S. The pink looks too vibrant to me to be montana Pink Perfection or montana Odorata. It's too light to be Tetrarose. The pink also seems to have more of a violet tint, which would rule out Marjorie. There are several other pink possibilities too. Do you know which montanas the nursery carries? That would help narrow it down.
For the white with pink bar... it's mindboggling trying to figure out which one it would be! Do you remember if these were in full sun, part shade, etc.?
