Cant seem to find anything on Francis!
I did notice Alice Forster and John Ball age 12 on the 1841 Census with Francis/Hannah though.
WILLIAM/MARY Wharton Baptised St Lawrence, Darlaston;
HANNAH Worton, 17 Feb 1808
MARIANNE Wharton, 11 July 1819, abode Butcroft, Father a Miner
PAMELA Worton, 25 Dec 1827, same details
THOMAS Wharton, 21 March 1830, same details ( buried 18 Jan 1832 age 2, abode Butcroft)
Large gap between Hannah and Marriane, maybe others born elsewhere.
