Using Google maps I can see that Knockenpower is a very rural area.
Usually, the enumerator assigned a number to each house but generally there was no significance to the numbering, it was just the enumerator's way of identifying the different households. So it will probably be difficult to establish where exactly Patrick and his family lived.
However, on the house and building return form it does show a Public House at No. 7. It is possible that somebody in the local area would know where there might have been a Public House at that time.
As regards where Patrick would be buried. There may be some records, I've attached a link here which might be helpful to you.
And just in case you don't already have it, here is the death of Patrick.
