There's banns at St B, Bishopsgate on 16, 23, 30 Oct 1842 as well.
And a set in December 1841, where George is George Recks Wright. A note in the margin says married 27 March 1842, but that has been crossed out. Did they turn up to the church on that date, but one of the congregation could give just cause or impediment? Link if you have access to Ancestry
https://www.rootschat.com/links/01tus/Of the first set (June 1839), the 3rd reading doesn't have vicar's initials by date, maybe that never happened because of objection at 2nd reading?
Was Harriet's mother still alive and someone was objecting to what would have been a bigamous marriage? Otherwise why all these failed attemps?
