Hmm?
Well, it looks like a second marriage for Benjamin (42) as there is a 19 yr old daughter born in London and Emma the wife is only 26.
Ben's POB is Derbyshire, Emma's Liverpool, and the two younger children, age 3 yrs & 9 mths are Birmingham so its difficult to say where they may have married.
My instinct leans towards the Ben who married in Q1 1856 in Melton Mowbray marrying Kezia Warrington, they are both from Leics and in 1861 living in Scalford which is in the Melton Mowbray district. The childrens births also appear to be registered in Leics (Barrow on Soar district & Melton Mowbray district).
You need to rule out the Ben/Kezia couple so asking for a look-up of the marriage, possibly in Barsby (Kezia's POB), Scalford where they are living, or in the Thorpe Arnold registers (Ben's POB), would hopefully settle that.
Then, if that rules out the Glover/Greaves couple the best thing would be to get the birth certificate of one of 'your' Ben's children, Alfred and Emily, to pin down the mother's maiden name and so lead to the correct marriage.
If I find anything else that looks like it fits I'll be back.
