Thrulines confusion for the Wind's of Durham County

[Seelife]

Hi folks, I have to say upfront, I am new and confused about the significance of DNA Ancestry Thrulines. I have also done a Big yDNA, but lets start with this.
I have I think, shown that there are several Wind families in Durham county in and about the late 1600s and certainly through the 1700's. They later morph the name to Winn. They are clearly focussed in NE England and I have found no connection to Welsh Winn/Wynns. My own Winn family line (WIND-1) hits a brickwall at about 1735 with a William Wind of Lamesley.
It was origionally thought there was only one line of Winds connecting to a William Wind born 1731 in Lumley (WIND-2). Many of the Ancestry trees show this, but I believe they are incorrect as I have I shown that these families are separate via family bith date records.
However, I always thought there was a common ancestor linking the two families and indeed some of the other NE England Winds.

On Ancestry Thrulines, I keep getting suggestions for relatives that suggest a connection with the WIND-2 line, usually in the range of 9-15 cms. My thoughts are that these connections are quite far out and likely due to some wayyyyy older ancestor.  But how much weight can be placed on these connections that are 5-8th cousins etc.
My own yDNA has a deep Scandinavian connection, and I am trying to sift out significant family connections that can shed some light on how these guys got to England probably in the Danish migrations etc. So, just how much can one trust these DNA suggestion/connections.

For now, I am looking a little closer at 2,3,4 th cousin connections of 100-200cms on my Parental side trying to find a way into the tangled mess of the Wind families.
Sorry for the long post, but any thoughts or suggestions  are quite welcome

EDIT - apologies, I meant to post this in the DNA subforum, if its easier please move the post, thanks.

Thrulines are based purely on trees not  the DNA results. They are just hints to potential common ancestors but have nothing to do with where the DNA came from.

Personally I don't trust any hint or thruline suggestion as I can't be certain the tree(s) they are based on are correct, well researched or just a copy and paste taken at face value from an unverified/unsourced tree.

Sub 20cM matches could be false matches but they could also be genuine matches that are so far back they predate traditional genealogy records. As they are beyond 3rd cousin range and below the 20cM shared match threshold it can take a lot of work trying to rule them in or out and it may not be possible to do so anyway.

Hi Glen. This is exactly what I thought. Many of the Thrulines hints I am given are of trees make incorrect associations and conflate two or more families. In all fairness, there are so many Wind folk with similar names living in close proximity and very likely related somehow., its not easy. It is semi clear that "most" Winds in Durham are related somewhen. There are a couple of blowins from Yorkshire way that originate from a different lineage that add to the confusion.
However, my Winn/Wind "tribe" seems somewhat distinct given my yDNA result. I am sifting the 2-3rd cousin hints ATM, most are incorrect family trees but it may help to tidy up the lines a little and pad out families. Most of my work is painstakingly slow on Wikitree, not Ancestry.
Thanks for the insights, really helps.

Seelife, a bit picky but “Durham County” is in the USA. “County Durham” is in the NE of England.

My aplogies. As an ex Aussie, I'm not sooo familiar with the convention, but have been caught out in searches that suggest the wrong side of the Atlantic. Will try to be consequent next time.

 I've lost count of the number of threads I've seen on USA based boards claiming Lincoln in the UK is named after the American President. The fact Lincoln is pre Roman seems to escape many Americans. Anything remotely connected to a Lincolnshire place name is usually so far down the drop down of place names it's easier to type it out in full and forget the varied offerings Ancestry users have concocted over the years. Sadly not everyone checks and it's easy to accidently click the wrong place and have ancestors in the wrong part of the world.

There's a place in Lincolnshire called Haddington and also a place by the same name in Scotland, I have a set of census returns claiming my Haddington, Lincs ancestor lives in Haddington, Lincolnshire, Scotland, England. There's not much hope when things like that slip through and have been copied thousands of times over a number of years.
