We have accumulated several Y haplotypes for various families with surnames Grigg, Griggs, and Gregg/Gragg. We now have representation from early colonial families from both North and South as well as Australia and UK. Would like to include more lines currently living in UK and Australia. Other surname variations are also invited, e.g. Griego, Griggers, Driggers. We regularly compare results with the MacGregor study.
