Hello Did you ever find out about August and Nancy? I have a tree that that indicates Maria Nancy Michener born 1835 daughter of Jonas Michener married August Speakman, 2nd marriage, and they had the children you name. Problem with that is that she is also shown as marrying William McCallum, and there is a death 1900 04 16 in Kent of Nancy McCollum, born about 1830. I am not having any success finding her otherwise under either name, and no trace of August or the 3 Speakman children either. She is in the 1861 Census with her father as Maria b. 1835
