What are your KERNAHAN interests?? I don't see this spelling very often. My KERNAHANs were in New York state, USA in the early 1800's. An unknown KERNAHAN had the following children in Ireland: James, Nancy(m.William NICOLSON), Mary Ann (m.William HIGGINSON), Thomas (m.Jane BLANCHARD)--this is my line, and Alexander (m.Hannah ?) I have letters dated in the 1850's from the family in Ireland to the US. They were postmarked from Leitrim and Crookedstone. Could use all the help I can get!!
