"T. Rockford" is an error for "T. Rochford," which is to say Thomas Rochford & Sons, the nursery firm at Turnford Hall, Broxbourne, England: "Another good thing is Messrs. T. Rochford and Sons' White Flight, a snow white sport of Mrs. F.W. Flight. As a pot rambler for market it will be good, and would group splendidly with Paul's Scarlet Climber. How these Roses will behave outdoors can only be ascertaned by experience," The Garden, vol. 80, 1916, p. 261. Rochford's had also been responsible for the Multiflora 'Gertrude Rochford' of a few years earlier.

The error was probably originally committed by a writer at Gardeners' Magazine, whom we see in 1910 alluding to "T. Rockford's establishment at Turnford Hall," and who likely made the same error at some point in relation to 'White Flight', the error subsequently being picked up by others. As mentioned above, Turnford Hall was the Rochford establishment.
