— born in Canaan Twp., Morrow Co., OH:
6.  Joseph V. CUPP, b. 1842/3 

Lamont's death certificate gives his mother as Elizabeth DUNKELBERGER.  This has to be an error because his parents' marriage certificate shows he married Elizabeth SHAVER [SHAFFER].  The death certificates of two of Lamont's older sisters (viz., Eliza and Mary Ann) show Elizabeth SHAFER as their mother.  Death certificates are notorious for containing errors (please see this page), and a marriage certificate trumps one.  The other possibility is that Peter remarried, to Elizabeth DUNKELBERGER, after the births of Eliza and Mary Ann, but before the birth of Lamont.  I have not found such a marriage record.  The death certificate of Joseph should help determine which is the case.

Elizabeth may have been old enough to have mothered Melissa and Franklin, but she was only old enough to have been the mother of Nancy if she was born in 1815, not 1810.  The death certificates of these children should be sought, as well.

Still no Sarah.  She obviously chose not to live with her father — or perhaps it was her stepmother she was avoiding.

4.  1850 Census Every-Name-Index/Images (online at Ancestry.com, Image #9 of 30 — indexed "Cap"):  Canaan Twp., Morrow Co., OH, Roll M432_716, p. 367A, 255/257, enumerated 23 Jul 1850, official enumeration date 1 Jun 1850 (extracted by Diana Gale Matthiesen):

Peter Cup	45	M		Farmer		Pa

Eliza Cup	16	F				"
Angeline Cup	15	F				"
William Cup	13	M				"
Lamont Cup	10	M				"
Joseph V Cup	8	M				"

Elizabeth's age is clearly enumerated as 35, but this age is not in synch with the 1840, 1860, and 1870 censuses, which would make her age in 1850 as 39 or 40.

5.  1860 Census Images (online at Ancestry.com; Image #10 of 36):  Marion P.O., Richland Twp., Marion Co., OH, p. 386B, 335/327, enumerated 20 Jun 1860 (extracted by Diana Gale Matthiesen):¤

Joseph    "	17	m	Do			Do
Melissa   "	8	f				Do

Elizabeth's age is clearly enumerated 49, and if she is really 49, not 45, she is definitely too old to be the mother of Nancy, and almost too old to the mother of Melissa and Franklin.  The nine-year gap between Melissa and Joseph suggests Joseph really is her youngest child, so are these three adopted?  Or is just Nancy adopted?  Or is Nancy a grandchild (e.g., the illegitimate daughter of Angeline)?  Listed next to daughter, Sarah Ann (CUPP) CREASAP, who is listed four households from Peter's presumed sister, Julia (CUPP) DUNKLEBARGER.
