Rebbecca, There are 25 DUNNs indexed in "THE COVERT FAMILY". Some are obvious duplicates. The only Margaret is a Margaret C. The entry reads from *Child's ...."and Ovid Village p188 has James b1854 in Penna, with wife Margaret c." That is the only direct COVERT to DUNN I found; others were DUNNs connected with non Covert surnames. You may want to contact the Interlaken Historical Society to see if they can help. My contact there was Dianne Nelson at email@example.com or 607-532-9227.
