At the last meeting of the DNA Sig, we took a poll. This was a not statistically significant poll, but it was written and in person. The poll just surveyed what Genealogy & DNA company people actually were using. The list was limited to the items on the poll. There are other DNA companies out there, but they were not on the list.
This group,had Ancestry tree highest, but AncestryDNA and FTDNA were equal! We will repeat this little survey again.
