My ggg-grandfather Jeffrey/Geoffrey married one Ellen O'Keefe about 1790 in County Cork, Ireland. Ellen died young, leaving three children (Jeffrey, Ellen & Marianne.) Jeffrey and Ellen immigrated to America in the mid-1800's. The second marriage of Jeffrey to Hanora Lehane had a son Denis who is was my gg-grandfather. Marianne married a Kavanagh and remained in the Mallow, County Cork area. Her great grandchildren remain in the Cork, Cahirciveen, Galway areas. I know one of Marianne's sons was named Arthur.
