McManus DNA Research

DNA can help distinguish family lines, test proposed relationships, and point researchers toward a shared geographic origin. It works best when genetic matches are evaluated alongside church records, civil registrations, censuses, family histories, and other documentary evidence.

The full DNA research collection includes:

• Y-DNA and Big Y-700 research into direct paternal McManus lines
• haplogroups, SNPs, and marker mutations
• autosomal DNA for relationships across several ancestral lines
• mitochondrial DNA for direct maternal ancestry
• explanations and project notes intended to help interpret the results

Browse all DNA articles or choose a DNA type:

• Y-DNA
• Mitochondrial DNA (mtDNA)
• Autosomal DNA

For test-specific research, explore the Big Y-700 articles.

DNA results do not by themselves prove every generation of a family connection. Published conclusions should identify the tested line, explain the documentary basis for that lineage, and protect the privacy of living participants.
