Ann Taylor was married to James Greer, as per the Will of her father Arthur Taylor. 6 June 1687.
However, the will does not say how long they had been married.

NO ONE has a proof source giving Ann's actual year of birth. My speculation is:
1665 that year her parents Arthur/Margaret would have been 17 instead of 12/14 years old. And Ann still would have been old enough, age 15 in 1680 to have married James Greer, 38 years older.

The will is saying, James Greer, and the wife Ann (Taylor-does not give last name). dated 1687. Some researchers say they were married 1680. "they only had 1 son, John GREER, born 1688, same year his father James died."
THE WILL from several rootsweb.com Family TREES
"June 6, 1687. To all Christian people, to whom these presents shall come ...
I, Arthur Taylor, of Gunpowder River, in Baltimore County, Maryland, Planter, for and in consideration of natural love and affection which I have and do bear unto James Grear and Ann, his wife, as also for divers and other good reasons and considerations and hereunto especially moving and do by these presents, give, grant, alein, enfoff their heirs and assigns, unto James Grear and Ann, his wife, their heirs and assigns forever, 75 acres of land, being part of a greater tract of 300 acres belonging to the said Arthur, and called, "Arthur's Choice", lying and being situated in Baltimore County, and on the south side of a branch of the Gunpowder River, called Bird Run, beginning at a red oak standing on the said river and running from said oak bounding with the ... run ... east-north-east 53 perches by a line into the woods for length 300 ... thence by a line down west-south-west from the end south-south-east ... east to line 53 perches ...
Witness: Samuel Sickelman, Amos Thompson -
Signed Arthur Taylor (his X mark)."
(Hall of Records, Annapolis, Maryland, R. M. # H. S., Vol. 1, page 261.)
This same land was held in trust for the "orphan of James Greer named John" until he reached age. Neither James Greer or his wife Ann left a will that has been located...
HOWEVER, Ralph Terry has:
"Lawrence Richardson came into possession of the 75 acres of 'Arthur's Choice' as "custodian for ye orphans of James Grear and now in possession of Oliver Harriott." The word "orphans" indicates more than one child and advances the idea by many descendants that James Greer and Ann may have been the parents of Joseph Greer of Prince George County, Maryland, whose will was dated August 8, 1715; proved December 14, 1715. (Maryland Calendar of Wills, Vol. 4, page 41. Also see Maryland Calendar of Wills, Vol. 6, page 184.)Other information about Lawrence Richardson from MARYLAND GENEALOGICAL SOCIETY, February 1966, Vol. 7, #1, page 42.

Ann married 2 more times:
#2 Lawrence Richardson b: in Maryland
Married: BET 1690 AND 1713
#3 Oliver Harriett
Married: BEF 14 MAR 1714

I have now found the links from Arthur Taylor & Margaret Hill thru their son John Taylor, brother to Ann Taylor-GREER. to my grandparents:
Lula E. GREER who married Clarence Lee TAYLOR.

So it goes ...
Ann Taylor married James GREER and their son
John GREER married Sarah Day, and they had 3 sons,
William-Benjamin-Joseph and they had kids who married each others kids. The last of the kids thru these marriages was my g-g- grampa Ezekiel GREER JR. He married Rhoda Poynter
and their son Lemuel Cerwood GREER married Adeline Manis.
and their daughter was LULA E. GREER who married Clarence Lee TAYLOR who's mother was Levisa A. Lee-Taylor, who married WILLIAM H TAYLOR the son of William F Taylor, married to Eliz. Pate, and his father was John Peyton Taylor (Thomas Littlegrove Taylor married to Sallie McCrocklin was his brother)John Peyton married to Mary C. DAvis, and his father was John Taylor married to Ada Parker, and his dad was Thomas Taylor married to Mrs. Taylor, and his dad was John Taylor who was married to Unice ?-Taylor and this JOHN TAYLOR'S father was ARTHUR TAYLOR married to MARGARET HILL-TAYLOR... the same parents of ANN TAYLOR-GREER...

And my sources for these LINKS are: rootsweb.com SEVERAL GREER Family trees... and familysearch.org again several GREER TAYLOR family trees and then finally the best links were found right here on findagrave.com
Thank you all for your help and all your research that helped me FIND the double GREER-TAYLOR link...

There is DNA tests that name another son, Thomas GREER.
EMAIL received from a descendant of John/Sarah DAY-GREER..
Talking about the will of John Greer, from Onslow Co. N.Carolina.
"And WHERE is Thomas? He was born in 1723, around the time Elizabeth nee Greer Davice. I've seen this will. Ralph Terry has it posted on rootsweb under John Greer. My DNA results clearly show I am related to Thomas Greers siblings, and the siblings of his mothers line. (Nicholas Days line). Was he disowned? He went to North Carolina. Was he so well off his father didn't feel the need to leave him anything?
I have the same problem with his son, Bartley Greer. (Bartley did die in 1794, in his early 40s). He's not listed half of the time. But just as I have DNA matches for John & Sarah nee DAY Greer, I have DNA matches to Thomas Greers wife, Jane Dunlaps line, to her siblings and her father, and to siblings lines of Thomas Greer. I also match the two main Greer markers in the GREER project, y haplogroup "R-M222" and "R-M269" James Greer b 1627 Dumfries-shire Scotland who married Ann nee Taylor being the "R-M222" match and John Greer b 1788 being the "R-M269" match, a slight mutation of the R-M222. He and all his children have the R-M269 marker in their decendants.
I'm very confused as to WHY there is no paper trail.
Thank you for hunting down the will.

Your "far Fetched: speculation
IF James Greer and Ann Taylor had more than 1 son?
at the bottom of the "will of Arthur" it mentions that the same land is held in trust for the "orphan of James Greer, named John" until he reached age. Neither James nor Ann Taylor-Greer left a will. " But Ralph Terry speculates that they had another son Joseph GREER.

Reviewing the DATA I don't see any actual proof
That they did not have more than one son, John--- D:1688
See the first paragraph of this memorial...

Where is the source that says she only had one son?

And IF DNA TESTS are the ultimate PROOF then the above
DNA TEST results give another descendant to
JAMES GREER B:1627 SCOTLAND who married ANN TAYLOR
in Maryland..who died 1688
JOHN GREER B:1688 Gunpowder, Maryland, who married
SARAH DAY-GREER, daughter of Nicholas DAY/Elizabeth.
AND JOHN GREER DIED: 1752 Onslow Co. North Carolina.
There is a will...

AND THIS DNA TEST ALSO PROVES THE LINK TO JAMES GREER BORN 1627 DUMFRIES, SCOTLAND....
YES!!!!!

The family burial cemetery could very well be located on the "Arthur's Choice-south side of Gunpowder river known as Bird Run." which was where Ann was living when she died and still married to Oliver Harriett.
Bird Run River is less than 3 miles from Little Gunpowder Falls.

NOTE: The place of burial is an assumption on us Descendants, that they did lay our ancestors to rest on their own property. Someday maybe someone will be able to get a Dowser over their and find where our peoples final resting place is.
