This is the project page for the Common Mitochondrial  Genome of Descendants of Pierre (Peter) Morel/Jacques Landry. The Haplogroup connected to his profile is H1-C16239T.
His Descendants can be traced with reasonable certainty through Flemish/French Immigrants of Highgate Georgia , Georgia, into Bulloch and Bryan Counties, and then ultimately to farther horizons such as Florida, Texas and beyond.
There are 3 Morels on record who immigrated into the U.S. in the 18th Century. 1 was Elizabeth Morel (1700) into Virginia; 2 Peter Morels into Georgia in 1733 who would have sons named John. Helen Rice separated Peter Morel of Chatham County whose descendants can be found in Bryan County. Complicating our research is that the Morels from Chatham County also has several court filings on record. 
- MRCA = most recent common ancestor(s).
- cohort = a group of DNA samples all descended from the same MRCA.
- cohort-pair = two DNA samples from different cohorts that are tested against each other
- opposite autosome = the non-selected autosomal chromosome of the two which constitute an autosomal pair. In matches between two or more cohort-pairs, it refers to the illusion of a match between samples of one cohort-pair with another cohort-pair on the same segment of the same chromosome. The falsity of the match is revealed when testing a sample from the first cohort-pair against a sample from the second cohort-pair, which demonstrates that each cohort-pair contains a separate, distinct match on each of the autosomal chromosomes of the autosomal pair.
- valid match = a match between two DNA samples in which the minimum segment is 5 cMs, the minimum segment size for negligible false-positives.
- threshold match = a match between two DNA samples in which the minimum segment is 7 cMs, the historically accepted minimum segment size for a moderately confident likelihood of a single MRCA.
- multi-chromosomal match = a valid and/or threshold match between two DNA samples on more than one autosomal pair.
- ___ samples from descendants of Elizabeth Morel/Harvey-113 of Black Creek, Georgia  constitute Cohort 1.
- ___ samples from descendants of William Wise/Margaret of the town of Kincardine Scotlandconstitute Cohort 2.
- ___ samples from descendants of [[______]] of the town of ___ name="______">Descendants of ____________:___ ___ ___.</ref>constitue Cohort 3.
- ___ samples from descendants of [constitute Cohort 4.
- ___ sample from an unknown descendant of Mortel _____/Richard Harvey
- ___ sample from a descendant of [[____|_____]]/[[_____|_____]]
- ___ sample from a descendant of [[_____|_____]]/[_____|_____]] of _____
- 2 samples from descendants of [[_____|_____]]/[_____|_____]] of [_____].
- 1 sample from descendants of [[_____|_____]]/[[_____|_____]] of [Place].
Additionally, ____ samples from affiliated marital lines that match the relevant _____ samples along the paternal line are included, collectively referred to as "the marital samples."
DNA matching was undertaken at GEDmatch using the default measures for One-to-One Autosomal Comparison except for the minimum segment cM size which was set to a numerical value of 5, the minimum segment size for negligible false-positives.Documented false positives were likewise eliminated. When dealing with large data sets, telltale traces of ancient, degraded DNA commonality seem to be:
- statistically significant, valid matchesbetween samples from different cohorts; and
- matches between different cohort-pairs along the opposite autosome; and
- repetition of matches between different cohort-pairs on different segments of the same chromosome, particularly where those segments adjoin or are nearly-adjoined; and
- residual threshold matches.
As a rule of thumb, "identical by descent" blocks longer than 4 cMs date from 500-1,500 years, while blocks longer than 10 cM date from within the last 500 years.In my own experience, however, meaningful identification of "identical by descent" trends from significantly-large sample-groups has been limited to about 700 years.
The first series of tests establish percentages for two cohorts known to share [[_____|_____]]/[[_____|_____]] as the MRCA: Cohort 1A and Cohort 1B. The DNA split occurred in 1820 and 1823. _____ descendants of [[_____|_____]]/[[_____|_____]] were tested against _____ samples from descendants of [[_____|_____]]/_____revealing:
- a 72% valid match rate;
- a 47% threshold match rate;and
- a 33% multi-chromosomal match rate.
The second tests determine common marital lines that preceded the DNA split of 1820-1823, with Cohort 1 being tested against various samples from the marital lines to reveal:
- ▲triangulated matches▲
- 1) There are 6 degrees of Separation in a direct link between me and Richard Harvey who is married to Elizabeth (Morel) Harvey . We also see 6 degrees of Separation in a direct link between me and their son Isaac Harvey.
- There are 10 Degrees of Separation between me and Mark Richardson 
- I have no idea why Mark Richardson kit doesn't show up for me on gedmatch.
- Through the Relationship Tool, we see 12 Degrees of separation if a Direct" connection between me and Tery Bell. What this means is the connection is between genetically linked family members, not marriages.

- Sits on the 14th Chromosome
- There are no connections between me and William Harvey, Jr. from Maryland. 
- Interesting, though not a direct line, there is a "connection" between William Harvey, Jr. and me through my father from Pennsylvania and his mother's ancestors through marriage. 
- There is a sketchy 19 degrees of Separation between William Harvey Jr. and Hannah Starling 
- No gedmatch between me and Hannah Starling,
- 2) There are also DNA links between descendants of William Harvey - who may be the same man as William Harvey, Sr. - and Margaret "Peggy" Wheeler - who may be a second wife [New England]
Though they might have a connection with each other, after working my way through 1), I think we've dispelled the DNA connection between the New England and Georgian Harveys. I believe Mark Richardson took his account off Gedmatch because as I've said, I can't find him there. I'm disappointed that I can't access his information. On the other hand I am deeply impressed with what Terry Byrd has accomplished and will use it on my Torrey ONS study as well as we continue collecting and categorizing genetically linked "Cohorts." Every profile with common names like Jones, Wise and Harvey should have one of these. Helen how do you find these cool sourcing tools?
- Finally, there are DNA links between descendants of Thomas Harvey and Cassandra Gott and descendants of Richard Harvey, Sr. and Elizabeth Morell.
Even before doing the Gedmatch between me and The Gotts, through the "Relationship" tool, there's a connection by marriage on both our sides of the family -- Step family. (See )
This is fairly persuasive proof that William Harvey, Sr./ William Harvey and Richard Harvey, Sr. share a common ancestor, and that the Montgomery Co. Harveys, the Bryan Co. Harveys and the Baltimore Co. Harveys are all related.
I'm not seeing the correlations at all. What I'm seeing is that there are completely different branches of Harveys represented here and I'm not entirely sure the best way to sort them out.
Helen, you and I are matched, with our common ancestors beginning with Richard Harvey and Elizabeth Morel. I did compare both you and me with John Bowen and at least as far as I could tell there isn't any matches. I didn't see any with Hannah Starling either. I suspect they are attached to a different Harvey. What is interesting is the Harvey John Byrd points to in Oglethorpe Georgia, though I'm not sure how "nearby" it is. I'm going to open up a profile for John Henry, a new "Freeholder" in 1938-39 in Ft. Frederica who left by 1741 to see how it fits. We can disconnect him if it doesn't work with the surrounding evidence. He's a real person so it's okay to make a profile for him whether or not he remains as Richard's father. But Helen, I would absolutely love to see you and me get on the same page.
