Im looking for more information on; Mary Cross was born on December 27, 1745, in Ireland. She had one son with Richard Keays in 1787. She died having lived for more than 100 years. She died on December 18, 1847, in Caherconlish, Limerick, Ireland, at the age of 101..... I know she had at least one son that left for North America, my 3rd Grandfather and he died in Ontario Canada.
I cant confirm her date of death /birth but seems unlikely that she lived to 101
Hi Faye, I havn't found Mary Cross' death. But I have found people related. In the 1911 Census a Richard married quite late. He married in Dublin but his address is Caherconlish. In 1901 he was still in the same place with his sister Jane.
Looking in the find a grave site the Keays are buried in Abingdon Cemetery. there maybe older grave but not listed.
