Majority of early Irish emigrants to America were Protestant Ulster Scots.

Evidence

Part of the explanation for the popular identification of Irish and Catholic lies in the strange story of the so-called Scotch-Irish. As has been stated, the majority of Irish immigrants to America in the eighteenth century and for the first third of the nineteenth were Presbyterians, descendants of Scots who had been settled in Ireland beginning with Cromwell and carrying on through William and Mary. The label “Scotch-Irish” was unknown in Ireland. Many Protestant Ulsterites had intermarried with native Irish women, and their children grew up as simply “Irish.” While they were members of a favored “race,” they had the same grievances with the Church of England and the British commercial and landholding system as did the Catholics. — Noel Ignatiev, How the Irish Became White, 143

Categorization

• QUESTION: The claim that Protestant Ulsterites had ‘the same grievances’ as Catholics is presented briskly — worth checking whether this refers to grievances in Ireland or America, since that materially affects the argument.
• XREF: connects to: Pre-Famine Irish emigration was neither uniformly poor nor uniformly English-speaking — Noel Ignatiev, How the Irish Became White, 138; Cromwellian land confiscation transferred most Irish land to Protestant settlers — Cedric J. Robinson, Black Marxism_ The Making of the Black…, 1588
