Miss Newcastle's name derived from that of an English city known for its coal production, and she was productive and long-lasting in both her racing and broodmare careers. After winning 15 of her 130 starts over seven seasons of racing, she then lived to produce 12 named foals. All were starters, reflecting creditably on their dam's hardiness, and nine were winners, including two stakes winners and one stakes-placed runner. Her best was Faneuil Boy (by Bolinas Boy), whose 22 wins from 108 starts included nine stakes races.
Both multiple stakes winner Faneuil Hall (named for the historic marketplace and meeting site in Boston) and stakes-placed Faneuil Girl are full sisters to Faneuil Boy, and they are the sources of the primary branches of Miss Newcastle's family. The elder of the two, Faneuil Hall, won 18 of 74 starts including four stakes events before carrying on the family traditions of longevity and fecundity by producing 15 foals, all of which started and 11 of which won. Hall of Reason (by Bold Reason) was a Grade III winner while the Native Charger colt Celebrated became a stakes winner in Belgium, but neither were of any importance as sires. It was left to Bold Boston, a daughter of Bold Forbes who ran unplaced in her only start, to carry on her dam's legacy, which she did by producing the stakes-winning fillies Tivli (by Mt. Livermore) and Lu Lu's Lullaby (by Palace Music) among her five foals.
Tivli was the superior of the two as a racer, and she was superior in the paddocks as well, producing Grade III winner Reunited (by Dixie Union) and stakes winners Deal Breaker (by Dixieland Band) and Wind Tunnel (by Summer Squall) among her 13 foals. In turn, two of her daughters have gotten in on the family act: unraced Dance Lively (by Kingmambo) is the dam of Japanese Group III winner Live Concert (by Singspiel) and English listed stakes winner Charleston Lady (by Hurricane Run), while Reunited produced Code of Honor (by Noble Mission) as her eighth foal.
Faneuil Girl was not as hardy as her brother and sister, making only 11 starts, but she made up for it by producing five stakes winners. The best of the bunch on the track was 1984 Matron Stakes (USA-I) winner Fiesta Lady (by Secretariat), and Faneuil Girl also had multiple Grade III winner Faneuil Lass (by Somebody II) and Grade II-placed stakes winner Land Rush (by Nijinsky II) to her credit.
While Fiesta Lady had the fancier pedigree and racing credentials and did become the second dam of multiple Grade I winner Thorn Song, Faneuil Lass had the better broodmare record, producing eight winners including Grade III winner Sam Who (by Lypheor) and stakes-placed Palestrina (by Al Nasr). Her daughter Breeze Lass (by It's Freezing) is the connecting link to the present; besides her stakes-winning daughter Afleet Lass (by Northern Afleet) and three stakes-placed runners, she is the dam of the winning Unbridled's Song mare Bluegrass Belle, dam of Pee Wee Reese.
Overall, Miss Newcastle's family is more notable for being prolific and hardy than top-class, but it has produced several high-class runners when given opportunities with upper-end stallions, and it has produced plenty of horses capable of earning their hay and oats. There are far worse things to be said of a family than that, and with a little luck, the descendants of Miss Newcastle will be putting coals on the fire for some time to come.
