Within the Blelack family tree, Blackbird N37 has had the most influence. She was bought privately from the Massie family along with many other senior cows and her daughter T22 has had great success in the herd. The Blackbird lines are easy calvers, fantastic mothers and good on their legs.

Other Blelack lines include Jayne Erica, Ergessa, Jury Erica and Princess Champers.

Shadwell Jayne Erica D160 sired by Shadwell Black Baroque A048 and is a granddaughter of Jayne Erica S48 of Blelack (pictured at 3 years old).
