According to the Hawkes Hunter by Bettye Waher, the Kerry Waterford pattern was introduced during the 1920s and cut in the "anglo-irish style of the 19th century." I have a picture in this publication that I could copy and send to you, if you would like to see if it is the same pattern.
I'm enclosing a bibliography on Hawkes that might be of interest to you. Many of these titles can be ordered through interlibrary loan at your local library.
I looked through our guides to American cut glass and didn't see any other references to the Kerry pattern, but these listings on Hawkes in the bibliography may be more revealing.
