"Baretta St. Bourbon"

If you look this lovely found rose up on HelpMeFind Roses ...

. . . you will find some lovely photos, courtesy of Janelle Michel -- along with a historic illustration of a rose that someone thought this might be:

'Gloire de Margottin'

-- Hybrid Perpetual, 1887.

Does anyone know who suggested that identification?

I gather that Fred Boutin, who found "Baretta St. Bourbon" suggests it is a double version of 'Gloire des Rosomanes.' (which is mostly why I bought it).

I notice that 'Gloire des Rosomanes' is the only recorded parent of 'Gloire de Margottin' -- and that the illustration of GdM has leaves that are a dead match for the leaves of "Baretta St. Bourbon" (and pretty neat looking, too).

Also -- There is no listed source for 'Gloire de Margottin'. (And no photographs of it.) Does anyone know if it is extinct?

(Frankly, breeding records from those early days are "iffy." I suppose it is possible that 'Gloire de Margottin' really IS a double sport of 'Gloire des Rosomanes' ("Ragged Robin"). There's probably no way to know.)

Photos to follow in "comments" because ... you know ... they won't post here. But I suggest you also check the HMF entry on "Baretta St. Bourbon".
