Entered		Result
17 Aug 1862	27d 3m 1y	21 Apr 1861
(Calculated birthdates should always be prefaced with "ca." — you can't be certain the person who calculated their age did it correctly.)

11.  State of Ohio.  Certificate of Death:  Eliza Straub.  Bureau of Vital Statistics, Reg. Dist. No. 815, File No. 4403.  Informant:  Mrs. R.S. Dombaugh, Marion, O. [nee Alice A. Straub, daughter of deceased].  The certificate mistakenly gives Eliza's father as "Wm. M. Straub," but gives her mother as "Catherine Ayers." 

12.  Saturday, 17 Jan 1914.  "Obituary: Straub."  The Marion Daily Star (Marion, OH), v. XXXVIII, n. 43, p. 2 (online at Ancestry.com):

******************************** *           OBITUARY           * ******************************** Straub — The deceased, Eliza Ann Straub, was born in Delaware county, January 11, 1839, being the fourth child of Mr. and Mrs. William Osborn.  Mrs. Straub was the widow of John Straub, to whom she was married July 23, 1854.  Her death was caused by a complication of diseases, January 4, 1914.  She was aged seventy-four years, eleven months and twenty-three days.  To Mr. and Mrs. Straub were born seven children, four of whom are living.  They are Mrs. J.C. Schaaf, of Prospect; Mrs. R.S. Dombaugh, of Marion; Mrs. J.P. Augenstein and Mrs. W.M. Hoke, of Waldo.  She also leaves two sisters and one brother, ten grandchildren and four great-grandchildren, and many other relatives and friends, who mourn her death.  She was a member of the Reformed church of Waldo, coming to that church from the United Brethren.  The only consolation that is left is the sweet realization of the fact that our loved one is at rest.

13.  J. Wilbur Jacoby.  1907.   A History of Marion County, Ohio, and Representative Citizens.  Biographical Publ. Co., Chicago.  Biographical sketch of Robert S. Dombaugh (son-in-law of John and Eliza). 

14.  Email from Connie Jones McGuire, who owns the family bible of Eliza's parents and says:

I have little pencil drawings that she made in 1850 of her cabin and also the name of her friend Sara Boyd.

15.  Allen L. Potts, compiler.  German's to Marion County, Ohio (online at HeritagePursuit):

Name	Birth Date Death Date	Birth Place Death Place	Father Mother	Imm. Date	Spouse Marriage Date
Straub, Johann Martin	Mar 24, 1837	Horrheim, Wuerttemberg	Straub, Johann Michael Bauer, Magdalena	1848Pr	Osborn, Eliza Jul 23, 1854

I'm afraid a bad connection has been made here.  Johann Martin STRAUB is not the John STROUB who married Eliza OSBORN.
