2.  1850 Census Index/Images (online at Ancestry.com; Image #2116 of 204):  Germantown, Philadelphia Co., PA, Roll M432_824, p. 246A, enumerated 6 Aug 1850, official enumeration date 1 Jun 1850 (extracted by Diana Gale Matthiesen):¤•

180	204	Samuel Stroup	25	M		Manufacturer		Penna
		Joanna    "	23	F				"
		Louisa    "	4	F				"
		John      "	1	M				"
		Susan Schaeffer	22	F				"
	205	John F. Swain	35	M		Shoe Maker		Maryland
		Sarah     "	44	F				Penna
		Peter Stroup	16	M		Shoe Maker		"

Sarah SWAIN is Johanna's mother, but John SWAIN is too young to be Johanna's father, so I suspect that Sarah was widowed by Johanna's father and that John SWAIN is either her brother-in-law or her second husband.  I suspect the latter, which may mean that Susan SCHAEFFER is Johanna's sister and that, thus, Johanna's maiden name was SCHAEFFER

3.  1860 Census Every-Name Index and Images (online at Ancestry.com, Image #205 of 440 — Samuel is indexed "Saml C Stroup" while, oddly, the index shows the head-of-household to be "Elizabeth Clair"):  Germantown P.O., Philadelphia (Ward 22), Philadelphia Co., PA, Roll M653_1173, p. 205, PN 205, enumerated 13 Jul 1860, official enumeration date 1 Jun 1860 (extracted by Diana Gale Matthiesen):¤•

1479	1448	Saml C Straup	35	M		Wool Sorter			Penn
		Joanna	32	F					do

		Francis	11	M					do

		Elisabeth	7	F					do
		Edward	0?/12	M					do
		Elisabeth	64	F					do
	1449	John Swain	44	M		Shoemaker			Maryland
		Sarah	54	F					Penn

The elder Elisabeth is Samuel's mother.  Sarah (__?__) SWAIN is Johanna's mother, but John SWAIN is too young to be Johanna's father.

Our subjects' daughter, Lizzie STROUP (æ 17, b. PA), is living next door with the DAVIS family as a "domestic servant."
