I am tracing a William Comans son of Jeffery and Catherine (nee Heffernan) Comans who comes from near Cashel. Jeffery comes from Knockavilla and Catherine from Clonoulty. William was born around 1815, Catherine remarried James Comans about 1821 and the family emigrated to Australia in 1838.I was wondering if your William may have been related to Catherine and her first husband.
