Scotch-Irish Americans in the context of "Scottish Americans"

James McHenry (November 16, 1753 – May 3, 1816) was an Irish American military surgeon, statesman, and a Founding Father of the United States. McHenry was a signer of the United States Constitution from Maryland, initiated the recommendation for Congress to form the Navy, and was the eponym of Fort McHenry. He represented Maryland in the Continental Congress. He was a delegate to the Maryland State Convention of 1788, to vote whether Maryland should ratify the proposed Constitution of the United States. He served as United States Secretary of War from 1796 to 1800, bridging the administrations of George Washington and John Adams. At the time of his death, McHenry owned 10 slaves, most of whom either worked as household servants or maintained his estate.

British Americans usually refers to Americans whose ancestral origin originates wholly or partly in the United Kingdom (England, Scotland, Wales, and Northern Ireland and also the Isle of Man, the Channel Islands, and Gibraltar). It is primarily a demographic or historical research category for people who have at least partial descent from peoples of Great Britain and the modern United Kingdom, i.e. English, Scottish, Welsh, Scotch-Irish, Orcadian, Manx, Cornish Americans and those from the Channel Islands and Gibraltar.

Based on 2020 American Community Survey estimates, 1,934,397 individuals identified as having British ancestry, while a further 25,213,619 identified as having English ancestry, 5,298,861 Scottish ancestry and 1,851,256 Welsh ancestry. The total of these groups, at 34,298,133, was 10.5% of the total population. A further 31,518,129 individuals identified as having Irish ancestry, but this is not differentiated between modern Northern Ireland (part of the United Kingdom) and the Republic of Ireland, which was part of the United Kingdom during the greatest phase of Irish immigration. Figures for Manx and Cornish ancestries are not separately reported, although Manx was reported prior to 1990, numbering 9,220 on the 1980 census, and some estimates put Cornish ancestry as high as 2 million. This figure also does not include people reporting ancestries in countries with majority or plurality British ancestries, such as Canadian, South African, New Zealander (21,575) or Australian (105,152). There has been a significant drop overall, especially from the 1980 census where 49.59 million people reported English ancestry and larger numbers reported Scottish, Welsh and Northern Irish ancestry also.

The Rockefeller family (/ˈrɒkəfɛlər/ ROCK-ə-fell-ər) is an American industrial, political, and banking family that owns one of the world's largest fortunes. The fortune was made in the American petroleum industry during the late 19th and early 20th centuries by brothers John D. Rockefeller and William A. Rockefeller Jr., primarily through Standard Oil (the predecessor of ExxonMobil and Chevron Corporation). The family had a long association with, and control of, Chase Manhattan Bank. By 1987, the Rockefellers were considered one of the most powerful families in American history.

The Rockefellers originated in the Rhineland in Germany and family members moved to the Americas in the early 18th century, while through Eliza Davison, with family roots in Middlesex County, New Jersey, John D. Rockefeller and William A. Rockefeller Jr. and their descendants are also of Scots-Irish ancestry.

Lancaster County (/ˈlæŋkɪstər/; Pennsylvania Dutch: Lengeschder Kaundi), sometimes nicknamed the Garden Spot of America or Pennsylvania Dutch Country, is a county in the Commonwealth of Pennsylvania, United States.

As of the 2020 census, the population was 552,984, making it Pennsylvania's sixth-most populous county. Its county seat is also Lancaster. Lancaster County comprises the Lancaster metropolitan statistical area. Lancaster County is a tourist destination with its Amish community being a major attraction. The ancestors of the Amish began to immigrate to colonial Pennsylvania in the early 18th century to take advantage of the religious freedom offered by William Penn, as well as the area's rich soil and mild climate. They were joined by French Huguenots fleeing the religious persecution of Louis XIV. There were also significant numbers of English, Welsh and Ulster Scots (also known as the Scotch-Irish in the colonies). The county is part of the South Central region of the commonwealth.
