Curraghmore are Townlands, there is both East & West. In the Parish of Currans, Poor Law Union of Killarney
Ballinskelligs was a townland in the Parish of Prior, in the
Poor Law Union of Cahersiveen.
A poor law union was an administritive area no more than 12 mi. from name city and would include any Parish's, townlands, villages within that area.
There are too many 395 O'Shea's in Kerry, and 75 of them in the Killarney area but only 43 in the Cahirciveen area.
Be proactive addresses are sufficient for mail delivery, no postal code's required. As there are 43, you can send to just obvious males. I would send at least 10, if not more. Stamps are pretty reasonable. Also if you change your email change it on Ancestry as well as no point someone responding but not being able to get in touch.
In the 1881 Commercial Directory is a Bartholowmew
OShea of Cahirciveen who is a Tailor
Bridgeet OShea china dealer
Jeremiagh OShea, grocery
