Improved Kieffer or Kieffer is one parent of Douglas (I’m not sure which but am nearly 100% sure it’s the old fashioned kieffer) and Duchess D’angoulme is the other parent. Douglas pears are typically smaller no larger than 3/4 of a pound Douglas Pear. My improved Kieffer can easily top 1 pound. Kieffer can get much larger @39thparallel has given me very large Kieffer before. Duchess D’angoulme can produce very large pears. Duchess pears are easily over 2 pounds
"The original pear tree Duchesse d’Angouleme was observed by M.Anne Pierre Andusson, growing in a farm garden in Anjou. Recognizing the qualities of this pear he procured several scion to graft. Later he sold the trees, in 1812, under the name of Poire des Eparannais. In 1820, he sent a basket of the fruit to the Duchesse d’ Angoulême, with a request to be permitted to name the pear in honor of her. The request was granted, and the pear has since borne its present name. Duchesse D’Angouleme pear is one of the largest of the pears we offer, can attain an enormous size. When well grown, the Duchesse D’Angouleme pears flesh is white, buttery and melting with a rich, delicious flavor. Some fireblight resistance. Bears early and regularly.

Thompson, in Elizabethtown, New Jersey, on a standard tree taken from the nursery of Mr. William Reid. It was forwarded to us anonymously, and we consequently felt some doubt about the enormous proportions; but, on application to Mr. Reid, the well-known nurseryman there, we received the following note:Description

Duchess D’angouleme.
Elizabethtown, N. J., Nov. 28,1855. J. Jay Smith, Esq
Dear Sir: The specimen of Duchess d’Angouleme Pear which you refer to, the outlines sent you by Chas. Davis, Junr., of this place, grown by Thos. R. Thompson, of Elizabethtown, is correctly described. The measurement was 15 inches longitudinal circumference, by 13 1/2 inches, as represented. This Pear was brought to my place by the grower, to look at before being eaten. I had heard of this Pear before I saw this specimen, but having so many fine specimens, I took no notice of it until I saw it; I at once thought the size exceeded anything I had ever seen, even putting me, as you observe, in mind of a monstrous specimen I saw at some exhibition, made out of wax. It was very solid and heavy, and, to all appearance, Juicy and perfectly melting; the weight is correct, having been weighed by several scales in town, viz: 1 lb. 12 ozs.
Yours, etc, Wm. Reid.

The Duchess is so large, that we have availed ourselves of the space to figure again that growing favorite, the Sheldon, of which Dr. Brinckl6 has kindly favored us with a better description than has yet appeared.

History
The Sheldon Pear is a native of Wayne County, New York. The original tree stands in the town of Hunn, on the premises of Major Sheldon, and sprang from seed planted by his father nearly forty yean ago. Two other trees in the vicinity, one on the farm of Mr. Norman Sheldon, and the other on that of Mr. Wisner, are also said to be seedlings bearing fruit very similar to the Sheldon. They have been carefully examined by competent judges, who assure us that they present no appearance of ever having been grafted or budded. And yet, no one who has seen the fruit from these three trees, can for a moment entertain a doubt as to their perfect and entire identity. The only way of reconciling the discordant facts and statements of the case, is to adopt the more than probable conclusion, that two of them are unworked suckers from the remaining one. Such, I have been credibly informed, is now the conviction of Major Sheldon.
A description of the Sheldon was published in Honey’s. Magazine of Horticulture for June, 1851, and in the Horticulturist for January, 1853. "- Duchess D'Angouleme And Sheldon Pears
