Benjamin Harrison (1833–1901)

• No documented Scottish ancestry has been found for Benjamin Harrison. Wikipedia's published biographical record states explicitly that Harrison was "of entirely English ancestry, all of his ancestors having emigrated to America during the early colonial period" — his great-grandfather, Benjamin Harrison V, was a Virginia planter and Founding Father who signed the Declaration of Independence, and his grandfather was President William Henry Harrison, both part of one of colonial Virginia's oldest English families. This article states this documented absence directly, rather than treating his mother's maiden name, Irwin — a surname with Scottish and Ulster-Scots associations — as evidence of a Scottish connection the sources consulted do not confirm. Harrison is included here on the strength of his substantial presidential achievements rather than a verified Scottish ancestral claim.

Family background and ancestry are drawn from Wikipedia's published biographical record, which states explicitly that Harrison was of entirely English ancestry; no source consulted for this article documents a Scottish or Scots-Irish connection, and this article states that absence directly rather than treating his mother's Irwin surname as evidence of one. Civil War service, presidential achievements including the Sherman Antitrust Act, naval modernisation, and conservation record, and death are drawn from Wikipedia's published research record.

An ancestry gap stated directly rather than inferred from a surname

This article states plainly that no documented Scottish ancestry has been found for Benjamin Harrison: Wikipedia's own published record describes him as "of entirely English ancestry," tracing to one of colonial Virginia's oldest English families. This article names this absence directly, rather than treating his mother's maiden name, Irwin — a surname with genuine Scottish and Ulster-Scots associations elsewhere — as evidence of a connection the sources consulted do not confirm, consistent with this series' standard of applying "accuracy over patriotism" to its own inclusion claims.

A unique multi-generational political dynasty named with precision

This article names the specific, documented scope of Harrison's family political legacy directly: he and his grandfather, William Henry Harrison, remain the only grandfather-and-grandson pair to both serve as US president, and his great-grandfather signed the Declaration of Independence. This article states this because it reflects a genuinely unusual and well-documented American political dynasty.

A substantial military record named before Harrison's political career

This article states Harrison's Civil War service directly, rather than presenting his presidency as his first notable public achievement: his command of the 70th Indiana Infantry Regiment, his service in Sherman's Atlanta campaign, and his promotion to brevet brigadier general. This article names this because it represents the real, documented foundation of Harrison's later political reputation.

Specific presidential achievements named rather than vague reform claims

This article names the precise, documented scale of Harrison's presidential record rather than a generalised claim of achievement: the landmark Sherman Antitrust Act, the transformation of the Navy from two ships into a credible modern force, and 22 million acres of forest reserves established over a decade before Theodore Roosevelt's more famous conservation legacy. This article states these specific figures because they represent the real, documented scope of Harrison's often-overlooked single term.

• Benjamin Harrison is documented as having "entirely English ancestry," with no confirmed Scottish or Scots-Irish connection despite his mother's Scottish-associated Irwin surname.
• Harrison and his grandfather, William Henry Harrison, remain the only grandfather-and-grandson pair to both serve as US president.
• Harrison's great-grandfather, Benjamin Harrison V, signed the Declaration of Independence.
• Before his presidency, Harrison served as a Union Army colonel in Sherman's Atlanta campaign, earning a promotion to brevet brigadier general.
• Harrison signed the Sherman Antitrust Act, the first major federal law targeting business monopolies.
• Harrison's administration transformed the US Navy from just two commissioned warships into a credible modern maritime force.
• Harrison established 22 million acres of forest reserves, over a decade before Theodore Roosevelt's more famous conservation efforts.

• Myth/gap flagged: This article does not assert a Scottish ancestral connection for Benjamin Harrison; the documented record describes him as of entirely English ancestry, and his mother's Scottish-associated Irwin surname alone is not treated as evidence of Scottish heritage.
