Without looking at the detailed maps (that show too much detail at times) the general areas known as Ballacross and Ballacrebbin almost merge. There is a Ballacross Cottage directly across the road from Ballacrebbin farm, and these are probably the buldings of that period. Many of the dwellings from that period and before have probably been lost so it is difficult to pin point exactly who lived where. The census enumerators would probably enter the address given by the household rather than what they though was correct. Neither party may have remembered what they gave 10 years previous!

Farrants Fort is only a few hundred metres from Ballacrebbin farm.
