I've hit a brick wall with my 2nd great grandmother, Anne Hewitt (née Michael). She died in Co. Cavan in 1875. Her father, John McMichael lived in Cavan at the end of his life and died in Drumconnick in 1866. This family is linked to the McMichaels (but I don't know how) who emigrated to USA and were extensively researched by Margory Clark Kapas (info can be found on the Internet)
