8.  George W. Wagenseller.  1904.  Tombstone Inscriptions of Snyder County, Penna.  Wagenseller Publ., Middleburgh, PA (facsimile hard copies available from HigginsonBooks.com; online at the Snyder County PAGenWeb site):

p. 83	CHAPMAN TOWNSHIP... GRUBB'S CHURCH CEMETERY...
p. 101	Troup, Moses, aged 75y. Troup, Catharine, w of Moses, b Sep 2, 1826; d Dec 20, 1858, aged 32 y 3 m 27 d. Troup, Elizabeth, w of Moses, d Aug 4, 1896, aged 73 y 9 d.

9.  Birthdate calculated using Ben Buckner's Birthdate Calculator.

Name	Deathdate	Age at Death	Result
Catharine TROUP	20 Dec 1858	27d 3m 32y	23 Aug 1826
Elizabeth TROUP	04 Aug 1896	09d 0m 73y	26 Jul 1823
(Calculated birthdates should always be prefaced with "ca." — you can't be certain the person who calculated their age did it correctly.)

The question, as always with Wagenseller, is the age at death wrong or is the birthdate wrong (i.e., which did he calculate)?  And in the case of Elizabeth, has age inflation taken place or was she fibbing about her age in the censuses?
