Five things we learned from a thrilling weekend of top jumps action

1 More success for a National Hunt sire-line of note

Montjeu sire sons have long been known as a brilliant conduit of class and stamina, making them perfect for National Hunt breeding. Indeed, before the weekend, no fewer than six – Authorized, Davidoff, Jukebox Jury, Montmartre, Scorpion and Walk In The Park – had supplied Grade 1 winners.

After the Dublin Racing Festival, that number now stands at eight as the first crops of Fame And Glory and Camelot yielded Commander Of Fleet and Sir Erec respectively.

Both winners are inbred 3x3 to Montjeu's sire Sadler's Wells, which is intriguing but also increasingly inevitable considering his ubiquity in jumps breeding. Commander Of Fleet is out of a mare by another son of the Coolmore legend in Saddlers' Hall, and the same can be said for Sir Erec, though in his case the maternal grandsire is Galileo.

Five-time Group 1 winner Fame And Glory, who died two years ago aged only 11, is looking a significant loss to jumps breeders as he was also represented by Meticulous and Embittered, second and third to Envoi Allen in the Grade 2 bumper at Leopardstown on Saturday.

It was a big festival for the Montjeu dynasty generally. Walk In The Park's son Min took the Ladbrokes Dublin Chase while Sir Erec led home a 1-2-3-4 for the sire-line, beating Gardens Of Babylon (also by Camelot), Surin (Authorized) and Tiger Tap Tap (Jukebox Jury). Rhinestone, from the final crop of Montjeu himself, was second to Commander Of Fleet.

Sir Erec is a rare Irish-trained horse sent over hurdles while still an entire. No back number on the Flat – he was a close third to Stradivarius in the British Champions Long Distance Cup in October – could he one day retire to stud, presumably under the Coolmore banner, to pass on his talent as a stallion?

2A French broodmare who is simply magic

Imagine if a stallion had supplied three high-class jumpers from just four runners under rules: we would be hailing him as a superstar.

Fee Magic has achieved exactly that, but because she is a mare in an industry obsessed by finding the next profitable male progenitor she has not attracted the same level of adulation.

The daughter of Phantom Breeze's breeding record certainly deserves having her name put up in lights. Her first foal, the Dom Alco gelding Grands Crus, was a fine staying hurdler for David Pipe and beat none other than Silviniaco Conti and Bobs Worth when he landed the Feltham Novices' Chase.

Incidentally, Grands Crus was once co-owned in France by Pierre Coveliers, whose son Ronny bred Saturday's brilliant BHP Insurance Irish Champion Hurdle heroine Apple's Jade.

Fee Magic's third foal Gevrey Chambertin, a brother to Grands Crus, won nine races for Pipe including a Grade 3 handicap hurdle at Haydock.

The dam's sixth produce is Le Richebourg, a six-year-old son of Network trained by Joseph O'Brien for JP McManus and a seven-length winner of the Frank Ward Solicitors Arkle Novice Chase on Saturday. That was the gelding's second successive Grade 1 strike, having taken the Racing Post Novice Chase last month.

Fee Magic's other runner under rules, the seven-year-old Buck's Boum gelding Nuits Premier Cru, has won five races in France for Emmanuel Clayeux and was a fair fourth in a Listed handicap hurdle at Cheltenham in 2017.

Le Richebourg and his siblings were bred by Jean-Marie Prost but French jumps breeding is a small world. Fee Magic herself was bred by Jacky Rauch, who with Clayeux is also responsible for Grade 1-winning chaser Al Boum Photo, whose granddam is a half-sister to Fee Magic, and last month's Grade 2 Lightning Novices' Chase scorer Dynamite Dollars.

Al Boum Photo and Dynamite Dollars are by Buck's Boum, the brother to legendary hurdler Big Buck's who stands alongside Network at Haras d'Enki in the west of France.

3Flat operation's fruitful expansion to the jumps sphere

The Cheveley Park Stud colours of red, white and blue could take on an extra significance at this year's Cheltenham Festival should Envoi Allen – winner of the Grade 2 Matheson Bumper at Leopardstown on Saturday – line up in the Weatherbys Champion Bumper.

The Gordon Elliott-trained five-year-old is a son of French-based sire Muhtathir, who commands a €5,500 fee at Haras du Mezeray.

Muhtathir has already sired a Grade 1 winner in Britain this season courtesy of Quel Destin's victory in the Coral Finale Juvenile Hurdle at Chepstow on Welsh National day. Muhtathir's son Doctor Dino is responsible for Sunday's Flogas Novice Chase winner La Bague Au Roi.

Envoi Allen was also bred in France by Bruno Vagne, also the producer of Espoir D'Allen, who won the Grade 3 Limestone Lad Hurdle at Naas last month for JP McManus.

Vagne is a cousin of Eric Vagne, the co-breeder of Bacardys who also raced last year's Coral Cup Handicap Hurdle winner Bleu Berry in the earlier part of his career.

Eric Vagne meanwhile is a brother to Patrice Vagne, who bred the Grade 1 John Durkan Chase winner Rubi Light together with Valerie Vagne.

Envoi Allen first made headlines when hammered down to Tom Malone for £400,000 at the Tattersalls Ireland Cheltenham February Sale last year, having won his four-year-old maiden at Ballinaboola comfortably. He is yet to be beaten, having also won a Listed bumper at Navan on his penultimate start.

Cheveley Park's other likely Champion Bumper candidate is Malone Road, sold by Stuart Crawford's Newlands Farm for £325,000 to Malone and Elliott at last year's Goffs UK Aintree Sale, having won his Loughanmore maiden in smooth fashion. He has won two bumpers to date by an aggregate 16 lengths and is unlikely to appear again before Cheltenham.

Chief Justice, another trained by Elliott for Cheveley Park, was not disgraced when fifth, beaten less than ten lengths, behind Sir Erec in the Spring Juvenile Hurdle on Sunday. He is a rare Graded performer over jumps for sprint sire Acclamation.

4 An unusual passage to India in classy hurdler's pedigree

It was nine years to the weekend that superstar Indian filly Jacqueline took her country's Derby under Richard Hughes, and the daughter of King Charlemagne made an unlikely impact on the jumps scene in Britain on the anniversary.

At the conclusion of her racing career Jacqueline was covered by India's then leading sire Glory Of Dancer and exported in-foal to Ireland in preparation for a star-studded date with Europe's finest, Galileo.

The resultant Glory Of Dancer gelding, Primogeniture, won races on the Flat for John Oxx, David O'Meara and Mary Hambro and is now plying his trade over jumps for Martin Keighley.

The mare's first foal by Galileo died, but the second was Lord Napier, formerly with John Gosden and now a rising star over obstacles for Peter Bowen, having won the Grade 3 888sport Heroes Handicap Hurdle at Sandown on Saturday by nine lengths.

The result of Jacqueline's third tryst with Galileo, Zenon, won two races for Gosden before being sold into Willie Mullins' yard for 120,000gns. He is yet to make his jumping debut but is quoted in ante-post markets for the Supreme Novices' Hurdle and Ballymore Novices' Hurdle at the festival.

Lord Napier joins a sizeable list of Galileo offspring who have emigrated to the jumps arena and met with notable success, one that also includes Cheltenham heroes Celestial Halo, Supasundae and Windsor Park.

Jacqueline returned to Coolmore last year for a cover by Camelot, source of Sir Erec.

5 Breeding clues abound for Grand National hopefuls

There were several clues for this year's Randox Health Grand National at Aintree when three of the 112 entries unveiled last week had prep runs at Sandown on Saturday – Folsom Blue, Give Me A Copper and Kilcrea Vale.

Folsom Blue and Give Me A Copper both finished fourth in their assignments.

The Old Vic gelding Folsom Blue shares his sire with 2008 Grand National winner Comply Or Die and 2010 scorer Don't Push It.

He was unlucky to be knocked off-course after the final fence in last year's heavy-ground Irish Grand National, running on strongly to finish a close fifth before being promoted to fourth in the stewards' room. That bodes well for his chances should he line up at Aintree this year.

Give Me A Copper, meanwhile, shares his sire Presenting with the 2011 hero Ballabriggs – one of three winners in the race for Trevor Hemmings, along with Hedgehunter (2005) and Many Clouds (2015).

Hemmings' three entries this year include December's Rowland Meyrick Handicap Chase victor Lake View Lad, bred by the recently deceased Peter Magnier on the same Oscar-Supreme Leader cross as Becher Chase winner Oscar Time, who was also second to Ballabriggs and fourth to Auroras Encore (2013) in the Aintree showpiece.
