I have found out this much - I emailed you, did you get it OK?
In the Guilds of Limerick listing for 1840, there are two Hickeys (John and Laurence) in the Nailers' Guild but no Edmond. There's no Edmond Hickey in Slater's 1846 Commercial Directory of Limerick as a resident but I do find that name and probably a whole family as Butchers in Newtown Market* - other names are: John, Patrick, Stephen and Thomas. I find the names John and Patrick in the 1837 Limerick City voters list but no Edmond and there's no Edmond as householder in Griffith's Valuation of Limerick City in 1851 (but LOADS of other Hickeys!). There is an Edmund Hickey leasing property in the townland of Bunlicky in the parish of Mungret from the reps of Henry Compton. Mungret is to the west of the city but Henry Compton also owned properties in High Street, Limerick.
*Newtown Pery was laid out and built on a grid plan in Limerick centre from 1760 onwards. I'm finding it hard to pin down it's actual location but it does seem to be where present-day Pery Street is and that is only 2 streets away from Catherine Street. So I think we can assume this is our family including the Michael that died in the US.
