Individual Details

Asa married Delila Wright, 21 Nov 1822, Roane Co TN.

I found Asa Richards in the 1830 Census, McMinn Co TN
Asa Richards: 2m -5, 1m 40-50. 2f 5-10, 1f 20-30, 1f 70-80 [quite possibly his mother Nancy]

The following appears to be a good match to the above family.
1840 Census, Calloway Co, KY
Asa Richards: 1m -5, 2m 10-15, 1m 50-60. 1f 5-10, 1f 10-15, 1f 30-40.

1850 Census, Rusk Co, TX, Hh 705
Asa Richards, age 61, b. VA [1789].
William F., age 22, b. TN
Gabriel A., age 21, b. TN
Mary A., age 16, b. TN [deaf]
Richard M., age 11, b. KY
Dilalah, age 48, b. NC
Mary E., age 16, b. ?Ga
I cannot explain the two Marys, nor why Delila was not listed following her husband. If Asa married Delila in 1822, Mary E. could not be a stepchild.
