"The Crosbie family had been Chief Bards to the O'Mores, chiefs of Leix for many generations. The original family name - Mac an Chrosáin (son of the rhymer) - reflected this occupation.
Seán Mac an Chrosáin and Pádraig Mac an Chrosáin changed their names to John and Patrick Crosbie in 1593. John Crosbie became Bishop of Ardfert in 1601 and his son Walter later became the First Baronet. Sir Walter Crosbie's son, Sir John Crosbie, Second Baronet, was "attained for his part in the 1641 rebellion" but apparently his lands were later restored to him. Sir John's son, Sir Warren Crosbie, Third Baronet, seems to have been the first to live at Crosbie Park and Sir Warren's heir and successor was Sir Paul Crosbie Fourth Baronet and father of Edward and Richard Crosbie. Sir Paul died in Noveber 1773 and Edward succeeded to the title.
The family estate at Crosbie Park was destroyed after the 1798 rebellion."
