2.  Census Index:  U.S. Selected Counties, 1840 (Broderbund CD-316):  can't find (couldn't find George's parents, either).

3.  Census Microfilm Records: Pennsylvania, 1850 (Broderbund CD-305, Disk 2):  Cumru Twp., Berks Co., PA, p. 339A, enumerated 12 Sep 1850 (extracted by Diana Gale Matthiesen):

Christian Straub	55	m	Miller	Penna
Anna Straub	50	f		"
George Straub	30	m	none	"
Peter Straub	21	m	none	"
Abraham Straub	17	m	none	"
Rose Straub	5	f		"
Ellen Straub	4	f		"

It appears Mary has died because George is back living with his parents, Christian & Anna.  Anna is too old to have birthed Rose and Ellen, and Anna's only child old enough to have been their parent is George.
