At least four ships have borne the name Irlam.[a]
The same company, Barton & Co. (actually Barton, Irlam and Higginson), owned each of the first three vessels, and each was a West Indiaman, sailing between Liverpool and the West Indies, primarily Barbados. There is too little information on the fourth to be able to confirm or refute the possibility that Barton & Co. also owned it. She did trade between Liverpool and Barbados.
