As far as I know, there is still no proof that Elizabeth Yeardley married Joseph Croshaw. She has been attached and detached from Joseph Croshaw a number of times, and as of today, she's back again.
Wikipedia has been edited to show her as Joseph Croshaw's wife, but Wikipedia's sources do not support the claim. (Anyone can edit Wikipedia--please use it with caution.)

For what it's worth, "Adventurers of Purse and Person Virginia 1607-1624/5" by John Frederick Dorman, Vol A-F, states Joseph was married 5 times and that most of his children are from the 1st (unknown) wife. It does not list Elizabeth Yeardley as a wife.
@Elizabeth Croshaw
@Maj. Joseph Croshaw
Amusing to see https://en.wikipedia.org/wiki/Joseph_Croshaw seeming to cite Dorman, John Frederick, Adventurers of Purse and Person, 4th ed., v.1, p.770) for the marriage.
From http://www.genealogy.com/forum/surnames/topics/yardley/311/
"As I posted elsewhere, the information regarding the marriage of Elizabeth Yeardley (or Yardley) and Joseph Croshaw seems to have sprung from the imagination of one John Monahan of Charlottesville, VA in a letter to the Huguenot Society of Manikin Town. What his connection to the Dumases and Croshaws is unknown. I have always regarded this letter with a grain of salt; his wife was the woman who claimed to be "Anastasia Romanov," daughter of Nicholas and Alexandra, and whose claims proved false. ..."
Name changed to 1st wife of Joseph Croshaw and the real Elizabeth Yeardley created. I'll relationship lock all of them.
Thanks--
The Wikipedia edits to genealogy information are a big headache. The Wikipedia page for Col. John West currently cites an unsourced Rootsweb tree as a source for one of his listed children, "Unity Ursula Susannah West."

The Yeardleys and Croshaws lived in a small world, and people wanted to believe there was a marriage. John Manahan (often misspelled Monahan) claimed to be an expert on Virginia genealogy. Unfortunately, he seemed to often be short on proof. He pretty much lost all credibility when he became the husband and chief enabler of Anna Anderson, who claimed to be Princess Anastasia Romanova. They both seem to have ended up with court appointed guardians. Search Google for "Anna Anderson." We need to put a stake through the heart of this one.
It's not clear. She was still alive when her father's will was written, 12 October 1627 (George Yeardley).
http://www.wellowgate.co.uk/Appleyard/yeardley.html
Her mother Temperance Flowerdew Yeardley West died intestate in December 1628 (per Virginia Immigrants and Adventurers, 1607-1635: A Biographical Dictionary, by Martha W. McCartney).
The three children of George and Temperance Yeardley (Including Elizabeth) appear to have been still living in 1630 when George's brother Ralph sued Temperance's widower Francis West. See p. 102, "Sir George's three children."

After 1630, I don't know if there is anything more.
Richard Croshaw is another Wikipedia invention (who writes there were 6 children and lists 8). I am cutting loose & letting him float.
Joseph Croshaw was only son and heir, died without issue, all those Croshaw lands ended up with the Wests:
"Born less than a month before his father's death was devised the bulk of his estate with reversion to the Wests if he died childless. This occurred and the Croshaw land passed into West ownership."
(no citation given unfortunately at http://wc.rootsweb.ancestry.com/cgi-bin/igm.cgi?op=GET&db=john_... )
I found a brief, typewritten paper called "Sir George Yeardley Governor and Captain-General of Virginia, and Temperance, Lady Yeardley, and Some of Their Descendants," one of several documents they have by a researcher named Frank Farmer.
All it has to say about Elizabeth Yeardley is this: "Elizabeth Yeardley, if she married, she probably did not live in Virginia."

To start with--DNA:
Unfortunately for the De La Warr Wests, there are three possible YDNA lines, and it's still not clear where the breaks in the line occurred.
Still....none of those lines match the descendants of Francis West of Duxbury.
Possible De La Warr West lines discussed here:

Francis West of Duxbury, here:

http://web.utk.edu/~corn/westdna/w20.htm
I'll see what else I can come up with.
Yes, here's the unrelated MA line:
http://web.utk.edu/~corn/westdna/west6.htm
W20 —Francis WEST, b abt 1606, England, d 1692 Marshfield, Plymouth Colony MA.
Wife: Margery REEVES, married 1639, Plymouth Colony

I'm curious if Jane West existed. She's not on the Wikipedia page. Which we know doesnt mean much in this area of WIki, unfortunately.
I'm curious if
As for the West/DeLaWarr lines for DNA. The West surname group was moved from the site you mentioned to familytreedna some time ago. the original site listed FamilyGroup 21 as the most probable correct line for the West/Delawarr Y-dna. I am a zero distance match to the person who was the top match for FG21 on the old site, and am now the second match in that group. With the discovery of William West's skeleton in the Chancel burials 3 years ago in Jamestown, there is a source of original dna. Earlier this year the JamestownDiscovery site reported that they believe they have discovered the femur of Thomas West/DeLaWarr in the excavation of the 2nd church. So, there is a second possible source of original dna to match. I have documentation leading me to Francis West, born 1726, Prince George, VA, died 1794 Amherst Co, VA. His wife was Elizabeth Bransford. I have searched for documentation of a connection for the last few years. The top person in FG21 has the same "oldest proven ancestor" as me. worked out our connection last month. We both are descendant from different children of Peter Francis West, the son of Francis West b1726. I have multiple generations of Francis West's in my patriarchal lineage, and believe it will connect to Francis West/DeLaWarr. from I may never find the paper documentation, but the DNA may prove, or disprove the connection.
Miles Files just has the standard information on Elizabeth Yeardley (living circa 1630, unknown after that). No info on Joseph Croshaw or any of his relatives.
The only Yeardley traced with descendants is Col. Argoll, and his line supposedly daughtered out. (If anybody bugged out to Maryland, especially farther than Somerset County, they might not be traceable.)
