I think it's far more likely that the breeder for this rose was Joshua Pierce, rather than Samuel Feast. C.M. Hovey gives credit to Pierce in 1847 soon after the rose was introduced, and Buist does also. Feast isn't credited with 'Anne Maria' until Ellwanger does so in 1879.

Given that Ellwanger wasn't even born until 1850, I'm inclined to go with Hovey and Buist on this one.

Art. IV. Descriptions of Eight New Varieties of Prairie Roses. By the Editor.

Mr. Pierce raised twelve kinds, brief descriptions of which he sent us last season; but, as they only referred to the color of the flowers, we thought it preferable to delay their publication until we could render them complete. Most of our plants have flowered finely this year, and we have been enabled to do so, and we now annex the following descriptions of each:—

Anne Maria.—Flowers, medium size, pale pink, with rose centre, cupped and very double: clusters, large, numbering twenty to thirty flowers, and rather compact: foliage, medium size, very pale green, undulated, slightly serrated, and rather smooth: spines, strong, pale green: habit, robust, vigorous and good. It is quite distinct from any of the others.
