1.  Marriage Record:

2.  Census Microfilm Records:  Pennsylvania, 1850 (Broderbund CD-305, Disk 5):  Greenwood Twp., Juniata Co., PA, p. 310, 2024/2054, enumerated  2 Nov 1850 (extracted by Diana Gale Matthiesen):

Nathan Stroup	28	M	Farmer	900	Penna
Nancy Stroup	22	F			Penna

Listed next to Nathan's widowed mother, Catherine (__?__) STROUP.

3.  1860 Census Images (online at Ancestry.com; Image #146 of 430):  Richfield P.O., Greenwood Twp., Juniata Co., PA, p. 618, PN 212, 1471/1, enumerated 30 Jul 1860, official enumeration date 1 Jun 1860 (extracted by Diana Gale Matthiesen):

Nathan Stroup	40	M		Farmer	2000	700	Penna
Nancy Stroup	31	F					"
Ann E	9	F					"
Julia	8	F					"
Nancy J	6	F					"
Nathan	2	M					"
Susanna	3/12	F					"
James Stroup	12	M					"

Given the age gap between Nathan and Nancy and the position of James STROUP on this list, I would normally assume that James was Nathan's son from a previous marriage; however, Nathan and Nancy are in the 1850 census with no children.  It may be that baby James was taken in by a member of his mother's family and did not return to live with his father until he was older.  Unfortunately, I can't seem to find James in the 1850 census.  Listed two households from Catharine (BAUMAN) STROUP, widow of Moses STROUP.
