Groom	Bride	Marriage Date	Performed by

Is this J.P. the Thomas NORRIS who is Mary's brother-in-law? 

2.  1850 Census Index/Images (online at Ancestry.com; Image #61 of 74):  District No. 4, Audrain Co., MO, p. 183B, 404/426, enumerated 12 Sep 1850, official enumeration date 1 Jun 1850 (extracted by Diana Gale Matthiesen):¤•

Almerna Davis	22	M		Farmer		Ia
Mary      "	22	F				Ia
Isabell   "	8/12	F				Mo

Listed next to David & Lucy DAVIS, who are probably Almarian's parents.  Back then, "Ia" was the abbreviation for "Indiana" (Iowa did not become a state until 1846, and it took awhile for people to shift to using "Ind" as the abbreviation for Indiana).

3.  1860 Census Index/Images (online at Genealogy.com, Image #8 of 26):  Hickory Creek P.O., Cuivre Twp., Audrain Co., MO, Roll 606 (Book 1), p. 760, PN 18, 124/132, enumerated 11 Jul 1860, official enumeration date 1 Jun 1860 (extracted by Diana Gale Matthiesen):¤•

A. Davis	40	M		Farmer		3000	Mo
Mary  "	35	F					Mo
Belle "	13	F					Mo
Ellec "	10	M					Mo
Alice "	8	F					Mo
David "	6	M					Mo
Mary  "	1	F					Mo
George Mills	13	M					Mo

"Ellec" appears to be an attempt to spell, "Alec."  Most of the ages and some of the birthplaces are off, but there can be little doubt these are our subjects — a big thank you to Patricia Summers Smith for pointing this record out to me because I had overlooked it.
