3.  1850 Census Every-Name-Index/Images (online at Ancestry.com, Image #9 of 153):  District No. 42, Jefferson Co., MO, Roll M432_402, p. 411A, 66/66, enumerated 9 Aug 1850, official enumeration date 1 Jun 1850 (extracted by Diana Gale Matthiesen):

Henry Clay Todd	31	M		Farmer		Ky
Nancy       "	33	F				Ky
Barton A Pearce	8	M				Ills
Julia A    "	7	F				Ills

4a.  1860 Census Every-Name-Index/Images (online at Ancestry.com):  Henry not found.

4b.  1860 Census Every-Name-Index/Images (online at Ancestry.com, Image #32 of 35):  Richwoods P.O., Big River Twp., Jefferson Co., MO, p. 690, PN 141, 1071/1061, enumerated 9 Aug 1860, official enumeration date 1 Jun 1860 (extracted by Diana Gale Matthiesen):

Geo Stroup	28	M		farming		50	Mo
Mary   "	21	F					"

Mary	6/12	F					"
Rudolph	4	M					"
Rufus	5	M					"
Nancy Todd	40	F		Spinstress			"
Bartlett Pierce	21	M		farm-hand			"

This record is hard to fathom.  Surely this is the George STROUP who married Julia Ann PIERCE, sister of Bartlett/Barton PIERCE, in 1856 [Jefferson County marriage records].  So, who is Mary?
