Oliver Hazard Perry (1785–1819)

Oliver Hazard Perry's mother, Sarah Wallace Alexander, is frequently described in older genealogical and commemorative sources as a direct descendant of Sir William Wallace, the Scottish hero of Braveheart fame, through a claimed line to "Colonel James Wallace, Laird of Dundonald." This article states plainly that this specific claim of descent from Scotland's national hero is an unsourced genealogical assertion, repeated in commemorative texts without supporting documentation, rather than a verified ancestral fact. What is documented is more modest but still genuine: Sarah Wallace Alexander was born in Loughbrickland, County Down, Ireland, in 1768, making her — and therefore Perry — Scots-Irish by documented birthplace, independent of any claimed link to Wallace himself.

Family background is drawn from Wikipedia's published biographical record for the documented English paternal Perry line, and from genealogical records (Find a Grave, and Ancestry/Geni family-tree aggregations) for the maternal Alexander line, including Sarah Wallace Alexander's documented birthplace in Loughbrickland, County Down, Ireland. The specific claim of her descent from Sir William Wallace is noted in these same genealogical sources as an unsourced assertion, and this article treats it accordingly, as claimed tradition rather than documented fact. Early life, naval career, the Battle of Lake Erie, later career, and death are drawn from Wikipedia's published research record.

A documented Scots-Irish birthplace, separated from an unsourced hero-descent legend

This article draws a clear, direct line between two different claims about Oliver Hazard Perry's mother: the documented fact that Sarah Wallace Alexander was born in Loughbrickland, County Down, Ireland, in 1768, and the separate, unsourced genealogical assertion that she descended directly from Sir William Wallace, Scotland's medieval national hero, through a "Colonel James Wallace, Laird of Dundonald." This article names this distinction because presenting the Wallace-descent claim as established fact would repeat an unverified piece of commemorative family lore as documented genealogy, contrary to this series' standard of accuracy over patriotic embellishment; the genuinely documented Scots-Irish birthplace is itself a sufficient and real basis for Perry's inclusion in this series, without needing the added, unsupported claim of descent from Wallace himself.

An English paternal line named alongside the Scots-Irish maternal one

This article states directly that Perry's paternal ancestry is separately and clearly documented as English, tracing to Edward Perry's emigration from Devon around 1650. This article names this because Perry's heritage, like several other figures in this series, is genuinely mixed, and presenting only the maternal Scots-Irish connection would obscure the equally real paternal English line.

A specific, documented naval achievement named with precision

This article states the precise, documented sequence of events at the Battle of Lake Erie: Perry's refusal to strike his "DON'T GIVE UP THE SHIP" battle flag, his transfer of command from the disabled Lawrence to the Niagara, and his resulting decisive victory, reported in his own now-famous words. This article names this sequence because it represents a concrete, specific military achievement rather than a general claim of naval heroism.

• Oliver Hazard Perry's mother, Sarah Wallace Alexander, was born in Loughbrickland, County Down, Ireland, in 1768.
• Older genealogical sources claim she descended directly from Sir William Wallace, Scotland's medieval national hero — an unsourced assertion this article treats as family legend, not documented fact.
• Perry's paternal ancestor, Edward Perry, separately emigrated from Devon, England, around 1650.
• At the Battle of Lake Erie, Perry transferred his command mid-battle from his disabled flagship to a second ship rather than surrender.
• Perry's younger brother was Commodore Matthew C. Perry, who later led the US naval expedition that opened Japan to Western trade.
• Perry declined to return fire in a 1817 duel provoked by a dispute with a Marine officer.
• Perry died of yellow fever on his own 34th birthday, during a diplomatic mission to Venezuela.

• Clarification: This article does not present Oliver Hazard Perry's claimed descent from Sir William Wallace as documented fact; this specific claim, found in older genealogical and commemorative sources, is unsourced and treated here as family legend. The documented basis for his Scots-Irish connection is his mother's birthplace in Loughbrickland, County Down, Ireland, which stands independently of the Wallace-descent claim.
• Content note: This article names Perry's paternal English ancestry directly alongside his maternal Scots-Irish connection, rather than presenting his heritage as uniformly Scottish.
