Is your Crawford yDNA line in the R1b-01A group? If so, have you tried to figure out how your branch might connect to the others in this cluster? One way to start untangling these relationships is to place our “earliest known ancestors” onto collaborative world trees such as FamilySearch and WikiTree, where connections and sources can be compared across projects.
Over the past few weeks, I’ve been working on identifying those earliest known Crawford ancestors from the R1b-01A section of the Crawford yDNA project. To make this easier to visualize, I located each ancestor on FamilySearch (adding their unique IDs) and, where possible, on WikiTree (profiles).
Below is an image of our section of the Crawford yDNA project spreadsheet. I’ve added two new columns showing the FamilySearch IDs and the WikiTree profiles I was able to track down.

Can you help connect any of these lines?
R1b-01A Ardmillan Earliest Known Ancestors
- James Crawford (1772-1854) – tests 979341, 520477 and 988737
- James Crawford – wife Margery
- FamilySearch: https://www.familysearch.org/en/tree/person/details/L5FF-1NF
- WikiTree: https://www.wikitree.com/wiki/Crawford-18048
- son James Crawford (1758-1836) – test 926985
- son John Crawford (ca. 1741-7- 1779) – test 934946
- probably descendant of John: William Nelson Crawford (1829-1907) – test 413080
- Edward Crawford (1762-1826) tests 87507 and 38087
- David Crawford (1710-1785) of Maryland test 636875
- FamilySearch: https://www.familysearch.org/en/tree/person/details/GRJL-7K3
- WikiTree: https://www.wikitree.com/wiki/Crawford-8466
By anchoring each of these lines to both FamilySearch IDs and WikiTree profiles, we create a stronger foundation for collaboration. These connections not only make it easier to compare sources but also invite other researchers to add documentation, correct errors, and share discoveries. As more Crawford descendants join the yDNA project and link their lines into these world trees, we’ll be in a better position to see where our families intersect—and perhaps finally untangle some of the long-standing mysteries in the R1b-01A group.
