No. & Sex	Age Class	Therefore Born	Individuals Inferred
1 male	10-15	1804-1810	= ?
1 male	19-25*	1794-1801	= Henry (b. 1794/5)
2 females	9 or under	1810-1820	= Daughter B = Daughter A
1 female	16-25	1794-1804	= Elizabeth (b. 1795/6)
1	person engaged in agriculture
*In the 1820 Census, the third column is age class 16-18 and the fourth column is age class 16-25; therefore, any individual in column three is duplicated in column four.  By subtracting the number in column three from the number in column four, you can create an age class "19-25."

Listed 14 lines from Conrad POWELSON (some assert that Elizabeth's mother is Elcey POWELSON).

5.  1850 Census Index/Images (online at Ancestry.com; Image #10 of 23 — indexed "Cremer"):  Franklin Twp., Coshocton Co., OH, p. 261B/522, 71/71, enumerated 17 Oct 1850, official enumeration date 1 Jun 1850 (extracted by Diana Gale Matthiesen):

Henry Creemer	55	M		Farmer	500	Va
Elisabeth "	54	F				Do
Mary      "	20	F				Ohio
Eliza     "	18	F				Do
Sarah     "	17	F				Do
William   "	16	M		Farmer		Do
Elisabeth "	13	M				Do
Umphra    "	21	M		Do		Do

I believe "Umphra" was a stab at spelling "Humphrey."  The fact that he is listed last, after the other children suggests he is either not Henry's child or he is Henry's child from a prior marriage.  Living next to presumed son, John CREEMER (æ 27, b. OH, wife Elisabeth), on one side; on the other side, living next door to Lewis POWLISON (n.b., some assert Elizabeth's mother to be Elsie POWELSON).
