Jane Campbell (Corneigle) - Corneigle Family

My mother, a Campbell, told me that she had an ancestress named Corneigle. She thought that her Christian name was Constance. She identified the Corneigles as a French Huguenot family in Northern Ireland. Can anyone please tell me where I may find further details of the Corneigles in Ireland, and whether Constance Corneigle has left any trace? jrleafy@hotmail.com
