Hubert Henry Schrader married Sara Dorothea Gardner [1854-1935], the daughter of Charles and Sara Ann (Young) Gardner of New York City, later New Utrecht [now part of Brooklyn], NY, and finally Patchogue, Long Island, NY. Hubert owned a painting (now in the NGA) of a cat by an unknown folk painter, probably dating to the latter half of the nineteenth century. Schrader's wife had inherited the picture from her father, and after her death it remained in Hubert's house until his own death in June of 1937.
