www.igp-web.com + Carlow is a great website for information about Carlow.

This is some of the information found there:

Letter 1894 Carlow District Lunatic Asylum, a letter regarding staff/attendant leaving prior to 1894

This was found under www.rootsweb.ancestry.com/~irlcar2

This was the only direct reference to an 'asylum'

The Carlow Workhouse opened in 11/1844, and the www.carlowhistorical.com has a catalogue of workhouse records put together in 1991 all inmates and staff recorded "Carlow Past & Present" Vol.1 No.4, 1993
presented to Carlow Co. Library

without knowing more I can't look further.
