DNA and the Brewers

Cynthia descends from the son of George b1670 named Howell who is head of Group F on the FT YDNA Brewer Project with dominant subclade I-Y23708.
Gary's Brewer descendant tester, 1st cousin Bill Brewer, has been active with the Brewer research and testing out to the FTBIGY700 placing him in Group E with ancestor Briant Brewer b1799 NC whose father was Thomas Brewer Jr. b1765 who married Lucretia McHugh. Bill sent me a download 100 pp paper 2 years ago on research maybe from David Brewer. The author tries to sort through all the various Thomas Brewers from the late 1700s and his work is very indefinite.
One line of Thomas's which he has uncovered is not 2 consecutive Thomas's but 5 Thomas's descending from John Brewer II, the grandfather of George Brewer of Brunswick, VA. They are
1. Thomas 1639-1698 VIrginia,
2. Thomas of Virginia 1680-1729,
3. Thomas of Virginia 1704-48 m. Elizabeth Godfry,
4. Thomas born Isle of Wight County, VA 1728 lived Halifax County, east NC died NC 1802,
5. Thomas born Halifax, NC 1765 died 1835 Indiana.
A co-admin for the Brewer Project named David Brewer, a couple months posted on the Activity feed an analysis of Group D headed by William Brewer born early in the 1700s. He and the admin, Hank Graham, do not think this William descends from George. Now he says that he will shortly post his research and conclusions about Group E which I say is the consecutive Thomas line and includes my ancestor, Briant Brewer b1799 NC.
Thomas line conclusions for all of us to consider. We would go ahead and disconnect Thomas Sr if it wasn't for waiting for better conclusions from the Brewer Project.
The Brewer Groups are remarkably close together in what they call the "Lanier Brewer Groups A,B, C, D, E, F, G, H." Gary counts only 1 difference between Lanier group G and Thomas Group E and 2 differences between Group E and groups A, D, F, and H. F is Cynthia's Howell.
Admins seem to argue that only one STR difference can separate 2 lines by several generations, meaning the 5 Thomas Brewer line from John II is the correct one for my Brewer line. But what about the other Groups which have 2 differences in their STR's to each other group? That is the problem and the admins are struggling with it. Hopefully this will be resolved shortly.
As for myself and my Group E, the Thomas line, it will end up coming from John II or George.

The above is paraphrased from the public Discussion here: Nathaniel Brewer, Sr.
