 The third chief of Clan Leask, Wilfred, signed a bond of Manrent in favour of William Hay, Earl of Erroll in 1456 and also resigned his lands in favour of his son and heir.From this point onwards the connection with the Clan Hay appears to have remained strong.When the Cheynes of Esslemont allied themselves with the Hays their bond was signed at the Chapel of Laske in 1499.
