This pedigree is inaccurate. Not sure what this horse's correct name is, but the true Greyhound P-5296 was foaled in 1944 and was by San Siemon and out of Lady Coolidge, just like it says on the photo for this horse. Also note that this horse's maternal grandsire is listed as Grey Hound (with a space), with the same AQHA number P-5296 and correct pedigree, but I believe it shouldn't have a space between the two words.
