9.  Paul J. & Barbara Midlam.  1985.  Marion County, Ohio, Cemetery Inscriptions (online at Heritage Pursuit):

STRAUB, John	1828-1887	Waldo [Cemetery]	Waldo
STRAUB, Eliza	1839-1914 w/o John	Waldo [Cemetery]	Waldo
STROUB, Elizabeth V.	d/o J. & E.A. d Sep 19 1861 Aged: 5y 5m 28d	Waldo [Cemetery]	Waldo
STROUB, Willie	s/o J. & E.A. d Aug 17 1862 Aged: 1y 3m 27d	Waldo [Cemetery]	Waldo

10.  Birthdate calculated using Ben Buckner's JavaScript Birthday Calculator.

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.  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). 

13.  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 STRAUB who married 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.
