More likely Swany than Alba Meidiland. Meilland seems to use their own named cultivars, listed as seedlings for their records. Alba Meidiland is absent of sexual parts -- at least in this area.
Swany is triploid, and diploid Alba Meidiland has more offspring listed, so it seems more probable to me Alba M. might be the seed parent, assuming disclosed parentages are accurate.
Craig Tufts, author of The BackYard Naturalist, recommends Bonica for wildlife friendly yards.
see: Tufts, Craig, The Backyard Naturalist, 1993, pub. by The National Wildlife Federation, p 71 "A Rose for All Seasons".
"offers lots of bloom over a period of months. It is very hardy, practically care free, densely shrubby, and bears heavy crops of hips through the fall and into the winter"
Tufts recommends placing Bonica near bird feeders--"offers safe harbor for many species of song birds..."
