1850 census of Perry Co., Ky, enumerated 26 Aug, lists on p. 13 as family #97/104:
William Gearheart, 18, farmer, b. Ky; Malinda, 17, b. Tenn; Felta, 18 (f); Roda, 17; Adaline, 13; Christina, 11; Jackson, 9; Arta, 7; Johnathan, 5; Rutha, 3. Felta through Rutha born in Kentucky.

The ages for William and Malinda are apparently off by about 20 years, since death records for several of the others in this family identify them as their parents.

1860 census of Perry Co., Ky, district 1, Hazard P.O., enumerated 25 June, lists on p. 34 as family 216/214:
Malinda Gearheart, 45, farmer, b. Tenn; Felt, 24 (m), laborer; Roda, 22; Adalne, 20; Christeena, 18; Jackson, 17; Arta, 15; John, 13; Jane, 11; Lewis, 2. All children born in Kentucky.

Note that Felt has changed gender, and many of the family members are 3 to 5 years younger than implied by the 1850 census. All the single females 15 or over on the whole page are recorded as “spinner” in the occupation column; this is probably a variant form of spinster and a way of saying they are unmarried, rather than this being a colony of wool spinners.

1870 census of Perry Co., Ky, Troublesome precinct, Hazard P.O., enumerated 18 Aug, lists on p. 14 as family #87:
Gahart, Valintine, 38, farmer, b. Ky; Malinda, 45, b. Tenn; Ladeline, 27; Jackson, 25; Joh, 23; Autey, 21; Lewis, 13. All except Malinda born in Kentucky.

Notice that Malinda hasn’t aged a day since the last census.

1880 census of Perry Co., Ky, district 82, enumerated 11 June, lists on p. 29 as family #233/240:

All listed as born Ky Ky Ky, although that conflicts with other records that Malinda was born in Tennessee. The marital status columns are blank for everyone.
