Doud
A North American phonetic respelling — the Irish Dowd with its w softened to a u.
An American respelling
Doud occurs chiefly as a 19th- and 20th-century American spelling of Dowd. The respelling of the English cluster -ow- as -ou- appears in American records of various Irish names; the precise mechanism by which individual Dowd / Doud variants arose in any given family is not systematically documented and often cannot be reconstructed from the records themselves.
A separate colonial line
Not every Doud family in the United States is of Irish origin. A distinct Doud line in New England descends from Henry Doude, who emigrated from England in the late 1630s and is recorded in Guilford, Connecticut. Descendants of this colonial English line are documented in the New England genealogical literature.
Most notably, Mamie Doud Eisenhower (1896–1979), First Lady of the United States, is a descendant of this colonial-English Doud line through her father John Sheldon Doud. Her Doud ancestry traces to Guilford, Connecticut, and not to Irish Ó Dubhda origin. This is one of the clearer cases in which a shared surname does not imply shared descent.
Is a Doud family of Irish descent?
For Doud families with Irish Catholic ancestry and a post-1830 emigrant record, descent from the Connacht Ó Dubhda through the Dowd / O’Dowd line is the usual case. For families whose Doud ancestors are recorded in 17th- or 18th-century New England, the colonial English line is the more likely origin. The distinction is normally resolvable through emigration records, Catholic parish registers, and the New England genealogical literature.
The longer clan history is on the O’Dowd page.

How the Variants Connect
Every spelling below descends from one Irish root — Ó Dubhda, "descendant of Dubhda." The tree traces how the name split across three regional septs and drifted into the anglicised forms carried today.
north Mayo & Sligo — the main sept
convergent naming — separate pedigree
* Duddy arose independently in both Kerry and Ulster — the Ulster line descends from the Cinel Eoghain, not from clan O’Dubhda of Tír Fhiachrach. † O Dondey is a 17th-century cartographic rendering from the printed maps of Boazio (1606) and Speed (1610); it is no longer carried as a surname.
Other Variants of the Name
If you carry the name Doud and your family story differs from what is written here — a tradition of descent we have not captured, a regional branch we have overlooked, an ancestor we should add — we would be glad to hear from you. This page is a living record, and the family has always been larger than any one account of it.
