I don't trust family traditions in such matters. In an article in American Gardening 19: 392 (May 21, 1898) the author reported that 'Harison's Yellow' was a seedling of 'Persian Yellow'; "Our knowledge of its origin came from Miss Harison, the grand-daughter of the originator, and who for many years and until recently, resided in Clinton Place, New York, and is now living at their old country home on the St. Lawrence."

Of course, this origin is impossible because 'Harison's Yellow' was in commerce before 'Persian Yellow' reached the West.

I think it is useful to note that some contemporary writers regarded 'Mme Desprez' (Desprez 1831) as having Noisette in its parentage. 'Jaune Desprez' (Desprez 1830) may share parentage with the other. This could explain the Noisette-like characters in 'Gloire de Dijon'. Folks back then were not clear on the concept of recessive characteristics, beyond some vague notion of atavism.

'Souv. de la Malmaison' is capable of bearing seed. 'Lucy H. Nicolas' (Nicolas) is one example.

If 'Jaune Desprez' or some other yellowish Noisette (Smith's Yellow?) was the pollen parent of 'Mme Desprez', even a self-seedling of 'Malmaison' might show some yellow, along with the climbing habit that was mostly latent in 'Mme Desprez' and 'Malmaison'.

Or if the unknown pollen parent of 'Malmaison' happened to be a white or yellowish tea, the same would be true.

I think it would be interesting to back cross 'Gloire de Dijon' (as pollen parent) with 'Souv. de la Malmaison'.
