Gandolf, thanks for the regular input. Good point about the associated trees, which I have realised in the past 10 days or so. It's certainly an ongoing learning curve. I have looked through all my 77 top matches and made notes on their trees, shared matches, cm's, and anything else that I see as relevant. I will post an update on my progress in the next few days.

Does anyone have any recommendations for figuring out matches? I have sorted different groups of Cornish matches who match each other on Ancestry with areas & surnames but I can't find the connection to any of them.
Is everyone in the Cornwall Genetic Community also?

You need to have access to a Chromosome browser. Ancestry doesn't have one. GEDmatch does, plus it has other useful tools. Matching by chromosome will get you better results than trying to match by name or location. Having a close relative tested - preferably a parent - would be handy.
Edited to add ; I used to do my family trees based on direct line descendancy. Also limited research to Cornwall and Australia only. With DNA research the wider the tree the better. You can have matches with fourth cousins and beyond. You need to go back five or six generations at least if you hope to find all your matches. Oh, it's well worth the effort!

Thanks! I might have to wait for a parent then because I don't think many of them are on GEDmatch & my lines are a WIP.

Hello, Jakis, I have been assigned (by Ancestry.com) to the Southwest Peninsula of England (with some uncertainty that I attribute to my father's non-English side of the family ) I have uploaded my test to Gedmatch, My Heritage, and Family Tree DNA. A sibling and some of my parents' cousins have tested, and that gives me the ability to pinpoint family groups. Zib

You will have matches already. There might be something of interest waiting for you. I have 13,082 matches above 6.5cM's and the list gets added to every day!

A sibling and some of my parents' cousins have tested, and that gives me the ability to pinpoint family groups. Zib I have a possible connection to the Southwest Peninsula. I was surprised to have it because it only comes through one grandparent. My brother's test should be back any day now & will probably test both of my parents. I have a first cousin match on Ancestry but they are a double cousin. I have GEDmatch but I can't tell recognise any of the Cornish matches on it bar one, I may use the segment search tool when family members have done the test also.

Grandparent level is strong.

The same Grandparent also had recent Irish, Scottish, French, English ancestry so the Cornish must be strong.

Yes, and Irish reports in for the Cornish. It is fluky thing.

Yes, I came in with 47% Irish & 4% British.

If you have only the one test to work with (i.e. yourself), my suggestion would be not to start with a particular line of ancestry (specific family surnaem).
Instead start with your closest match and try to establish the connection. If you are lucky, this will be a reasonably close relative (say a second cousin). Once you have established that a particular DNA test/kit matches a specific known cousin, then you have two established reference points (you and the cousin) and can use them to look for other tests that you both share in common. The Match Both Kits/Tests options in both Ancestry and GEDMATCh (and other sites also) is most useful here.
As you progress and establish progressively more definite matches, it makes it somewhat easier to figure out the potential relationship of any new test.
Unless all your ancestors for many generations come from a small population pool that is heavily intermarried, it should not be too difficult to identify further matches and gradually work out to the more distant cousin matches.
For most people born outside the UK but in one of the former British colonies, you will likely have a fairly mixed heritage which should allow you to narrow down matches into various parts of the family.
However if all (or a large part) of your ancestors are from a small grouping then it will be more challenging. Relatively isolated and small populations such as southwest Ireland, Orkney Isles, and probably even to some extent the Penwith Peninsula in Cornwall have a tendency to marry close to home all the time, with relatively little outside intermixing. As a result, DNA segments tend to be better conserved through the generations, which can on occasion skew the likely cousin estimate and can even mean that a match you might think is related to one of your ancestral lines is in fact actually from another completely different line (effectively a false positive for the first family line) that may have had a distant crossover with the first family.

Thanks for your help. My closest matches are from a different apart from a couple of double cousins. I am now working with one of my highest fourth cousin matches to find our connection, it looks likely to be Cornwall due to shared matches in common.

After about a year and a half, I have a new match today that is totally unexpected (keep testing, everyone!) It is to a fellow Bartle family member who is a 6th cousin twice removed and the first I find outside of my known Mary Bartle/Henry Semmons line from Crowan. My newest cousin is Australian while I am American. I am hoping to connect three different Bartle lines eventually (I feel confident that 2 line up) This cousin is on the line that I know, but it might take DNA to join the rest. I am ready and waiting Zib

My great-great-grandparents, Edward Harvey and Mary Semmons were the parents of 11 children. I have a new DNA match today to a grandchild of their youngest child, Thomas. I only mention this because this is my first shared match that links me to the line of William Harvey and Ann Trewhela's grandson Martin who settled in Australia. The rest, including my sibling, must all share Semmons DNA. This cousin and I inherited Harvey genes. I have been waiting to see something like this.
