1861 census - 47 is the schedule number, not part of the address.

1871 census - Robert & family, including Isaac aged 1, were at Ballamoda (cottage).

The next entry is for a Kelly family at Renscault house.

One has to be careful with these census entries not to confuse a building description with a building name.

You usally see the name of an area, farm, estate, etc. followed by a building description - cottage, farm house, private house, house, etc.

The majority of these descriptions are not identifable with modern building names.
