All the children of Allen and his first wife Rachel Oliver are recorded with him and his second wife Phoebe Collins in the 1900 census:

1900 census of Morgan Co., Ky, district 2, enumerated 22 June, lists on p. 19B as family #345/354:
Craft, Allen, 59, b. Oct 1840, Ky Ky Ky, farmer, married 42 years; Phoeba J., wife, 40, b. Apr 1856, Ky Arkansas Ky, married 20 years, mother of 8 children, 7 living; Fernando, son, 23, b. Aug 1876; Samantha, dau, 22, b. Oct 1877; Lula B., dau, 21, b. Apr 1879; Leslie, son, 17, b. July 1882; Dora, dau, 14, b. May 1886; Corda M., dau, 12, b. Apr 1888; Floyd, son, 7, b. Mar 1893; Ollie, dau, 4, b. Oct 1895; baby, dau, 0/12, b. May 1900. All children born Ky Ky Ky.

Note the discrepancy between the reported age and birthdate for Phoeba. The different numbers in the reported length of marriage suggests that they may each be reporting the number of years since their first marriages.

Samantha Craft married Leander Blankenship in 1895. He is also living with his parents in this census year, recorded as married. So her marital status should be either married or divorced rather than single.

I cannot find a marriage record for them in Morgan Co.
