From Mac Maghnusa to McManus
McMaghnuis.com is a gateway to the public McManus Family History archive and its companion historical and genetic research projects.
One connected research project
Follow the records, evidence, and family stories
McMaghnuis.com takes its name from an Irish form associated with the McManus surname and serves as a gateway to the broader McManus Family History project.
The main archive connects named people and family groups with places, parish registers, documents, photographs, historical stories, books, and DNA research. Its strongest concentration is Kilronan Parish in north County Roscommon, but the research follows McManus families and connected surnames across Ireland and through later migration.
Search people, families, places, parish records, DNA research, documents, books, and stories.
