10.  Richard Andrew THOMPSON, b. 1864/5

The scenario painted by the LDS Ancestral File for Mary Jane TODD has some problems.  It says Mary married Nathan HERNDON on 21 Aug 1847, followed by marriages to Arthur Monroe HICKS, then Richard THOMPSON.  While it gives no marriage date for her marriage to Arthur HICKS, it shows a son, Thomas Robert HICKS, born 1866, and a son, Franklin HICKS, born ca. 1870.  There is a recently widowed Mary J. HICKS (ae 30 — obviously a fib if she has a child 18 — b. KY) in the 1870 census of Jackson Twp., Ozark Co., MO.  She has these children:  Sarah J. (18, KY), Francis M. (16, MO), Abner L. (10, MO), Clowra W. (7, MO), Thomas R. (3, MO), Arter F. (3m, MO).  She is living next door to a J.W. THOMPSON (ae 25, b. KY, wife Honnor M.) on one side and an H.W. HERNDON (ae 25, b. KY, wife Caroline) on the other side.  But Mary married Richard THOMPSON as Mary Jane HERNDON, not Mary Jane HICKS, so there could have been no intervening marriage to Arthur HICKS.  Also, no son, Thomas Robert (who survived until 1961), appears in the 1880 census with Richard & Mary.  So… have two Mary's been mixed up here?

Richard THOMPSON Marriage: 1853 Spouse: Mary Jane TODD Birth: 26 Mar 1832 Source: patron submission

Richard's first wife, Frances BALLARD, was still alive and still married to Richard as late as the 1870 census, so he cannot have married Mary Jane TODD in 1853.

2a.  1850 Census Index/Images (online at Ancestry.com; Image #45 of 60):  Liberty Twp., White Co., AR, p. 464A, 351/341, enumerated 26 Nov 1850, official enumeration date 1 Jun 1850 (extracted by Diana Gale Matthiesen):

R Thompson	24	M		Farmer		Ky
Francis "	24	F				"
Willis  "	2/12	M				Arks

If Willis is two months old on June 1st, he was born between March 1st and April 1st.  Listed four households from Richard's parents.

2b.  1850 Census: Mortality Schedules (online at Ancestry.com):

Name	State	County	Age	Birth State	Death Month	Cause of Death
Thompson, Willis	AR	White	3M	AR	Aug	Cong Chill

Willis should have been five months old in August.  Given how easy it is, when handwriting is poor, to confuse "3" and "5," it seems likely his age at death has been mis-read.  None of Richard's brothers had a son Willis in the 1850 census, so it seems this infant has to have been our subjects' son.

3.  1860 Census Images (online at Genealogy.com; Image #58 of 61):  Falling Spring P.O., Ozark Co., MO, Roll 637 (Book 1), p. 464, PN 58, 383/383, enumerated 28 Jun 1860, official enumeration date 1 Jun 1860 (extracted by Diana Gale Matthiesen):

Benjamin S	9	M					Ark
William H	8	M					Mo
John W	6	M					"
Alexander W	4	M					"
Andrew	3	M					"
Barraba E	1	F					"

For the eldest son, the enumerator had written some other name beginning with "B," then scratched it out and wrote "Benjamin."  Listed two households from Richard's parents.  "Andrew" is Anderson and "Barraba" is, of course, Barbara.
