ONLY Mine ran away with the Group 3 Lacken Stakes at Naas on Sunday and in doing so recorded a treble of a kind. The daughter of Pour Moi was her sire’s first ever winner last year when she won a maiden at Cork. She then travelled to Newmarket to become Pour Moi’s first ever stakes winner, while at the weekend she became his first group winner.

Her victory also brings to mind the late Marguerite Weld who bred the filly and who will be remembered for many years to come as a most successful breeder, enjoying great success with a relatively small number of broodmares at any time. Mrs Weld was incredibly knowledgeable and also enjoyed great success as an owner.

A special moment, and one that I remember well, was when she owned and bred the Irish 1000 Guineas winner Nightime. That filly, trained by her son Dermot, was out of another mare that she raced, namely Caumshinaun. I know from conversations with her that Caumshinaun was quite a favourite of hers. Nightime’s son of Dubawi sold as a foal last November at Goffs to John Ferguson for €1.1 million.

Only Mine races in the colours of Mrs Chantal Consuelo Regalado-Gonzalez, and she is also the owner of Zhukova, the Group 3 Blue Wind Stakes winner at Naas this year and a daughter of Fastnet Rock. Zhukova is trained by Dermot Weld and is known to be a favourite of the trainer. Mrs Regalado-Gonzalez raced last year’s Oaks winner Qualify.

Another notable breeding success Mrs Weld enjoyed was that of Grey Swallow, the Irish Derby winner who was also an inmate of her son’s Rosewell House Stables. Originally based at the famous Piper Hill Stud outside Naas, Mrs Weld moved to Springbank Way on the Curragh in the early 2000s and died in April 2014 at the age of 98.

Only Mine has always been well regarded by Joe Murphy who purchased her at the Goffs Orby Sale for €80,000. In fact, before she had even won her maiden she was group-placed when beaten less than a length by Most Beautiful. Now she is a dual stakes winner and a hugely valuable racing prospect yet, while also being a top-class broodmare prospect.

She is the fifth foal of her dam Truly Mine, a listed winning daughter of Rock Of Gibraltar. Four of the five were named and all have run and won. The previous winners include daughters of Dalakhani and Rip Van Winkle. The mare’s sixth offspring is a two-year-old full-sister to Only Mine, named All Mine, while her yearling colt by Dawn Approach was catalogued last year for the Tattersalls December Sale but not offered.

Truly Mine did something that her daughter Only Mine also did, namely to be group-placed before she won a maiden. As a three-year-old, and on only her second start, she was placed in the Group 3 Lodge Park EBF Park Express Stakes. She later won a maiden at Leopardstown and trainer Dermot Weld kept his mother’s filly in training at four, a move that was fully justified when on her final start she landed the Listed Salsabil Stakes at Dundalk.

Truly Mine had been purchased as a yearling for €200,000 from Sir Edmund Loder’s Eyrefield Lodge Stud and she was one of a pair of stakes winners produced by the Barathea mare Truly Yours. That juvenile winner in France is also the dam of True To Form, a full-brother to Truly Mine, and his 11 victories included a listed race on the all-weather at Lingfield.

This is a wonderful female line and Truly Yours’ seven winning siblings include Dream Peace and Catcher In The Rye, both of which came close to winning Group or Grade 1 races. Catcher In The Rye, a son of Danehill, only raced four times and was runner-up to Clodovil on his final career start in the Poule d’Essai des Poulains, the French 2000 Guineas. The former Coolmore stallion is a Group 1 sire.

Dream Peace is a daughter of Danehill’s son Dansili and she was a Group 2 winner in France and a multiple Grade 1 placed mare in the USA. She was twice runner-up in the Diana Stakes at Saratoga, including on her final start. She was third in the E P Taylor Stakes at Woodbine in Canada, a race won by her dam Truly A Dream but that was before it was upgraded to Grade 1.

Truly A Dream, a daughter of Darshaan, was one of eight winners out of Truly Special, a group-winning daughter of Arctique Royale, herself out of Arctic Melody. This has been a truly outstanding female line and Truly A Dream’s other stakes winning sibling was the multiple Group 2 winner Wareed who was also placed in the Ascot Gold Cup.

Solo De Lune, a Law Society half-sister to Truly A Dream, is the dam of Group 1 winner Cerulean Sky (dam of Honolulu and grandam of Royal Bench, Mayhem and Memphis Tennessee), the Irish Oaks winner and Epsom Oaks runner-up Moonstone (the dam of Derby hopeful US Army Ranger), and the champion filly L’Ancresse who was runner-up in the Irish Oaks and the Breeders’ Cup Filly & Mare Turf at Santa Anita.
