townland of Rockmount

Hello,

I have a baptismal record for my great-grandmother's sister, Mary Foley, baptised 1852. The place of residence in the parish register for her parents, Henry Foley and Joan Cuggeran, was Rockmount. I have long worked with the understanding that the place name mentioned in a baptismal record (when one was named) was the residence of the family. Please correct me if that is not true.

No Foley was named in the Tithe Applotment Books of 1824 in Rockmount, although surnames of Cleary, Kennedy, Shaughnessy, McInertney, Finucane, Corbett, Egan and Hennessy were recorded in Rockmount. I know these names were the "occupiers" of titheable lands, and the actual heads of households within a townland were not really relevant to the purpose of the survey, as multiple families could have been living together in one dwelling place or two cabins on a plot of land, etc., and "occupier" and "head of household" were different and separate designations. However, I have not been able to establish a link with either Henry or Joan (aka Joanna and Susan) to any of those surnames.

Henry's father, Timothy Foley, was at Erribul in TABs. The place name of Rockmount disappeared by the 1842 Ordinance Survey, and so it does not appear on a map. I'm hoping to learn exactly where on a map this place would have been. I cannot find any reference to a map for this area connected with TABs. If I can find that out, maybe I can get a better handle on which family Henry and Joan would have been living with.

Furthermore, Henry was not named as "occupier" in the Griffiths Valuation of 1855, either, although subsequent children were born at Erribul, and Patrick Foley was head of household in Erribul for Griffith's. Clearly, Henry was not the first-born male. I have never found another head of household named Foley in Erribul except Patrick's direct lineage in both directions, and so I presume that any Foley who was born or lived or died at Erribul would be related to this line. Please correct me if I am wrong about that. So.... Two questions:

1. What place name took over where Rockmount would have been situated?

2. With whom were Henry and Joan living in 1852 when Mary was born?

Thank you,

Jeanne
