CARROLL Y-Chromosome DNA Surname Project
The goal of the CARROLL Surname Project is to distinguish between CARROLL ancestral lines, worldwide. Any reasonable spelling variant is included (please feel free to suggest a variant you feel I have missed).
To participate meaningfully, you will need to share your male direct-line ancestry either in the form of a pedigree or, preferably, as family group sheets.
Another option if you have a website with your Carroll family lines, please provide the address info and we can insert a link next to your name in the lineages and results page.
