There were Elizabeth Ewarts in my family which migrated from Derry Ireland. The earliest Ewart who came to America in my family immigrated in the 1700's so ours are not the answer. I do agree that it is very difficult to trace family to Northern Ireland. I know that other relations migrated at the same time, but I cannot tie them to my ancestor because of the issue in Ireland. The family lore is that these people were originally Scots who fled due to religious persecution, staying in Ireland, before leaving for America.
