Family on p. 25, The Genealogy of William Tobias Phillips. Elza lists three children, Louanna, Grant, and Jethro, who died in infancy. No dates, and no indication as to which wife they were by. Jethro was listed as age 6 in the 1880 census, though, so he didn’t die in infancy unless they reused the name.

Fleming served in the Civil War, in Company B, 54th Virginia Infantry.

1870 census of Floyd Co., Virginia, Indian Valley & Burks Fork district, enumerated 27 Aug, lists on p. 30 as family #198/186:
Phillips, Fleming, 37, farmer; Martha J., 19; Rosanna, 14; Venecia J., 12; Grant, 1/12, b. May. All born in Virginia.

1880 census of Floyd Co., Virginia, Indian Valley district, enumerated 5 June, lists on p. 12 as family #99/100:
Smith, Sidney, 28, farmer; Martha J., 29, wife; James N., 15, brother; Leander J., 1, son; Phillips, Delia, 8, stepdaughter; Phillips, Jethro, 6, stepson. All born Va/Va/Va.

(I’m putting the above in Martha Jane’s notes rather than in the family notes since it contains children from both of her marriages.)
