I had 5 minutes free this afternoon and dropped into the archives. At first sight, it's not that helpful. The licence was issued on 22 March 1792 to BR, 20, of Sheffield, to marry HT, 18, also of Sheffield, at Sheffield parish church. Note the date - you say they married in April 1793. I'm wondering whether this is because the record ran from Lady Day to Lady Day.
Since Hannah is a minor, as for that matter is Benjamin, it might be worth getting a copy of the allegation. I have that of my 3 x great grandparents in 1804. It gives the groom's age (22), marital status, parish and calls him a yeoman. The bride is only 18 and her father gives his consent to the marriage (it was a shotgun business) and gives his occupation. Both men sign their names.
You can order copies online through the Borthwick's website.
All the best
