I decided to see if any of the atDNA matches to Zachariah showing on Wiki are among my Ancestry matches. I didn't find any that I show a DNA match with, which is interesting, so I'll have to check our Gedmatch kits to show if we match on that site.
One of the Wiki atDNA matches for Zachariah does show a tree with Zachariah as the son of John Morgan and Hannah Morgan. John shows in her tree as a descendant of this John Morgan:
John Morgan
who is a descendant of the Edward Morgan descendant Terry Morgan referenced in one of his posts about believing Zachariah to be a possible descendant of Edward's.
Sir Edward Morgan, Lt. Gov. of Jamaica
Interestingly, Geni shows Edward's Y-DNA haplogroup as I2b1. Terry Morgan who was posting about the connections and the DNA evidence didn't provide his haplogroup, but the Morgan Y-DNA group on FTDNA shows Zachariah as I-M253. My own line from Col. Morgan Morgan shows in that group as R-M269.
So I searched and found that M253 is I1, and M223 is I2b1.

and from there it's all over my head. lol
https://www.geni.com/projects/I-M253-Y-DNA/34605
does show I2a2a - I-M223 (formerly I2b1)
as a subclade of I under I1 - I-M253. So, I think that means those two are related variations under a common umbrella.
If the person who listed their ancestor as Morgan Morgan from Wales in the Y-DNA group has his info correct and that branch is R-M269, then that branch seems to be unrelated to the other two as it doesn't show up on the pages where they are listed.
You'd 'think' (or I did) that all Morgans from Wales must be 'somehow' related, but it appears that may not be the case, which would explain why I don't have a DNA match on Ancestry with any of the atDNA matches on Zachariah's Wiki page.
However, no one in the FTDNA Morgan Y-DNA group is listed with haplogroup I2b1 and I wasn't able to match any of the Edward Morgans on their list with the one referenced in this discussion.
Zachariah, however, is on the list and shows:
Zachariah Morgan, b.c. 1776, NC Unknown Origin I-M253
Zachariah Morgan, b.c. 1770-75m Clay Co., Ky Wales I-M253
and my Morgan Morgan shows as:
Morgan Morgan ,1688 Glamorganshire Wales Wales R-M269
Y-DNA test results of male descendants of Zachariah seems to be the only way to sort out which Morgan branch he is from, if Terry and other are correct that he was a biological Morgan, not a Benton.
