Another name for Ann was Martha Ann Smith.
Ann is married to Elijah Harvey by 1841.
Ann married Elijah Harvey, son of Uriah Harvey and Jane Bright or George, on 14 Dec 1819 in Terling. (Elijah Harvey was born about 1793 in Terling and was christened on 25 Dec 1793 in Terling.)
There are two possible marriage dates for this marriage, in 1819 and 1825. I think 1819 is more probable and the 1825 date is guesswork as their eldest child is shown as Wiliam on the 1841 census.
