Is Amanda the 5-yr-old girl in the 1850 census with Jacob SCHANTZENBACH?

5.  1870 Census Every-Name-Index/Images (online at Ancestry.com, Image #1 of 51):  Shimersville P.O., Upper Milford Twp., Lehigh Co., PA, Roll M593_1361, p. 585A, PN 1, 8/8, enumerated 10 Jul 1870, official enumeration date 1 Jun 1870 (extracted by Diana Gale Matthiesen):

Schantzenbach John	58	M	W	Laborer	400	300	Pennsylvania
"       Kate	60	F	W	Keeping house			"
"       Elias	56	M	W	Laborer			"

One would have pegged Elias as John's brother, but danged if I can find him in earlier censuses — anywhere.  Is he really Elias?  Or really SCHANTZENBACH?  If Elias really is John's brother, then John cannot be a son of Jacob SCHANTZENBACK because there is no room for Elias in the early censuses of Jacob's household, though there is room for John.
