I don't have any info on Patrick and Thomas Kirwan, and didn't know about them until I got a letter from Mrs. Moloughney last week. I should dig out the notes I took from Slater's Directory for (I think) 1880. It has some names in Roscrea. Martin Kirwan was a prominent name in Roscrea, I know. Glad to finally know that someone else has heard of Chateau Kirwan. A cousin from Leadville, Colorado went down to the Denver Library two years ago and copied some info about the wine and sent it to me, but I don't have it here with me. Tom Fitzsimmons.
