4.  Messages posted to the Rose Family Genealogy Forum (online at GenForum.com).  See especially Message #7611.  Proof that Sarah (LONDON) SUMMERS was not the mother of Abner's children, found in papers relating to the estate of her brother, Amos LONDON, Jr., in Giles Co., TN, specifically, a deposition that includes:

D G Bills, aged about seventy years who answers and says - I knew Amos London late of Giles County, Tennessee for some fifty years before his death.  I knew him first in North Carolina then in Tennessee.  He never had any child or children born in wedlock and died leaving neither child or children or the representatives of such.  He had one brother only, his name was John London who died in Marshall County, Tennessee.  He left a good many children & among them was Sarah, who intermarried with Thomas Parks.  They are both dead and have two living children, viz., John L and James M Park.  One daughter of said Thomas and Sarah Park married Nicholas Tomblinson & she is dead and has left one child, I believe.  Amos London had three sisters.  One of them married Brice Jackson - Jackson & wife as I understand are both dead.  They left some children, but the number I can not tell.  One other of his sisters married a man by the name of Johnson Summers.  He died and she married a man by the name of Abner Rose.  They are both long since dead and she died without child or children or the representatives of such.  The other of Amos' sisters married a man by the name of Palmer.  As to Palmer and wife I speak principally from information and family reputation, but as to the children if any I can not speak from my own information but I am well satisfied that these four are the only brothers and sisters of the said Amos London and further this deponent says not. D G Bills Subscribed and sworn to before me on the 4th of March 1861 W B Holden (Seal) JP for Marshall County

D.G. BILLS has to be Daniel G. BILLS who is in the 1860 census of Marshall Co., TN (æ 70, b. NC, p.124A), with wife, Rachel [SUMMERS] (æ 67, b. NC).   Daniel Gersham BILLS (b. 8 Sep 1790, Surry Co., NC; d. 17 Oct 1862, Marshall Co., TN) married 3 Oct 1812, Surry Co., NC, to Rachel SUMMERS (c1793-1883).

p. 18	We have identified a Sarah Summers/Sumner, a Quaker, who was disowned 6 November 1786 in the New Garden Monthly Meeting of Guilford Co., N.C.  It was not specified why she was disowned but marrying out of unity (to a non-Quaker) could have been a reason.  This date is suggestive of the probable date of Abner's first marriage.
p. 19	We believe this Sarah Summers/Sumner was the daughter of Robert Summers of Surry County who died in 1779...
This belief, that Abner married a Sarah nee SUMMERS ca. 1786 appears to be the root of the errors surrounding Abner's wives.  As can clearly be seen from other (easily obtainable) evidence, Sarah (nee LONDON) SUMMERS was Abner's second wife, whom he married no earlier than 1807 and probably after 1810. The editorial "we" here appears to be including Christine (CICIARELLI) ROSE, the professional genealogist (owner of the Rose Family Association), who worked with the author to produce this book (Christine's husband is a descendant of Abner ROSE, as am I).

6.  Christine Rose.  6 Oct 2006.  Abner Rose Family.  Typescript.

As can be seen, the wife or wives of Abner Rose are at this time uncertain.  He may have had a first wife before Sarah Summers, and it is possible that Sarah Summers was a widow when she married Abner Rose.  It may be that she is the widow of John Summers who died in the early 1800s.

How has she missed the evidence I found in a brief search?
