I have just discovered that the marriage Register for Lilleshall is on FindMyPast but there is no marriage for Andrew to Mary so they either didn't get married or married in a different church somewhere else and the reading of the Banns took place in Lilleshall because it was possibly Mary's (or may be even Andrew's) Parish. It was not uncommon, if the couple came from two different parishes, for the Banns to be read in both Churches.
Sorry about that.
