The 1828 Marriage doesn't list any Perks witnesses,they being John & Diana Bough.

I'm aware of the Dudley Coleys but no relation as far as I can tell,mine are from King's Norton.
Edit:
I think we may be getting somewhere,there's a John Perks b.1813 B'ham,parents Thomas & Jemima,they had a large number of children most being christened in a batch in Oct.1830,one of them being a Thomas Millington Perks b.1816.
So we now have a Richard,Benjamin & Thomas all with middle name Millington (+ Henry in Salop) & Richard living with the brother (John) of Thomas M Perks.
