Daniel didn't marry until 1841, so we would expect him in the home, but he's in the wrong age class.

5.  1850 Census Index/Images (online at Ancestry.com; Image #20 of 30) — mis-indexed as surname "VAN CRESSUP" with no given name:  Richland Twp., Marion Co., OH, p. 127A, 843/850, enumerated 6 Sep 1850, official enumeration date 1 Jun 1850 (extracted by Diana Gale Matthiesen):¤•

Based on earlier censuses, Mary is fibbing about her age (she's at least 25).

*The county is not given on the original certificate, which describes the location of the land solely in terms of Aliquot, Section, Township, and Range.  The county names must have been added to the database at some later time, probably when the certificate data were computerized.

Co., Chicago, IL (online at Heritage Pursuit).  Biographical sketch of their grandson, Samuel B. CREASAP.  The bio states that Daniel CREASAP came to Ohio with his parents when he was about 16 yrs old (i.e., ca. 1833), but this does not jibe with the birthplaces of Daniel and his siblings as given in the 1850 and 1860 censuses.
