This Thomas was reportedly nicknamed “Chucklehead”.

Be careful not to confuse him with his brother-in-law and first cousin, Thomas E. Lewis born in 1821, son of William M. Lewis and Jane Perry.

Thomas and Nancy were first cousins.

1850 census of Morgan Co., Ky, enumerated 26 Aug, lists as family #433:
Thomas E. Lewis, 27, farmer; Nancy, 30; William, 6; John, 4; Francis, 2 (m). All born in Kentucky.

1860 census of Morgan Co., Ky, district 1, enumerated 9 June, lists on p. 15 as family #85:
Lewis, Thomas, 36; Nancy, 40; William E., 16; John S., 14; Francis F., 12 (m); Gardner, 8; Emeline, 6. All born in Ky.

1870 census of Morgan Co., Ky, Blairs Mill precinct, Bangor P.O., enumerated 22 July, lists on p. 8 as family #63/60:
Lewis, Thomas E., 48, farmer; Nancy, 51; Gardner, 18; Emeline, 15; Taylor, 22; Ellen, 17.

Note that Taylor does not appear in the previous two censuses, although he is the right age to be the son listed as Francis in 1850 and 1860. Based on later censuses, Ellen is his wife.

1880 census of Morgan Co., Ky, Blairs Mill district, enumerated in June, lists on p. 14 as family #119:
Lewis, Thomas E., 56, farmer; Nancy A., 59, wife; Gardner, 27, son; John, 34, son; Thomas J., 22, son; Jane, 84, aunt, widowed; Tolliver, Emma, 23, daughter, divorced; William, 2, grandson. All born Ky Ky Ky.

The relationship for Thomas J. Lewis must be wrong, since there is no match in the 1860 or 1870 censuses.
