Dear Brigid, We are researching the Christopher C. Farnan and Johanna Corcoran line. Grandson of CC and Johanna was Leo Emmanuel Farnan b. March 19, 1917 d. April 3, 1997. Johanna b. 1861 is John Corcoran's great aunt, a sister to his grandfather, John Joseph Corcoran b. 1866. We were sent pictures of CC and Johanna from another relative in Conception, MO. Hope to visit there in October.
