Struggling to find a corresponding marriage in Bath in timescale.
There was an 80yr old Mrs Miller, widow of Ingleby Miller, died at Shincliffe in 1842. If Ann's mum, then perhaps indicating Ann married later in life. Ann was possibly the one born 1799 to Ingleby Miller and Elizabeth Clark (to help gauge an approximate age for the W B Harvey too).
