I have been able to trace back to my 3rd Great grandparents Jeremiah Tierney and Margaret Walsh b.in Ireland. Their son Micheal Tierney b. 1846 possibly Limerick Ireland; d. March 25 1883 in Merriton (now St.catharines) Ontario. He Married Margaret Ellen Boyle on Jan.12, 1871 also in Merriton. This was his Second Marriage as he is listed as a widower on the Certificate. I have more if anybody wishes to contact me.
