I am looking to learn about colonial period immigration from Ireland to Virginia in the mid 1770s. My 3rd great grandfather, Luke MORAN, immigrated to Virginia. He may have been an indentured servant. Do any ships lists, manifests or the like exist for this time period? It is believed that he left Ireland around 1773-1774. I'd be interested in learning about this topic or any specific information about Luke Moran, if it exists. Thank you!
