The discussion about the pros and cons of FTDNA vs Ancestry is almost complete except for the point that FTDNA can provide 111 marker test where as Ancestry has only about 40 markers. The more information you have via the DNA test the better you can identify different branches of your lineage. For instance, in the Hempstead Jackson grouping we now have 30 participants. They represent three separate branches of this lineage. One branch came from England to New England and subsequently to Hempstead NY. Another migrated from England to Virginia at least as early as the previous branch. And the most recent is the branch that came to America via a British Red Coat in the Revolutionary war, then changed sides and stayed. Unique mutations in the 67 marker test has enabled us to distingush at least one separate sub-branch in this lineage. We have one participant that has tested at Ancestry that is related to the Hempstead lineage, but because of the limited number of markers at this testing site we cannot determine what branch he belongs to.
