Thank you for your suggestion. I had seen the marriage citation on familysearch.org, that and a posting on a Michigan Dibean marriage index is all the information I have. I also know of a Twamley family over on the other side of Chelsea, but none of the names or ages match up. Also, there is a Twamley Lake not too far from where my family lived at the time. I've also found another marriage of a Henry Twamley to Eliza Wanu on Dec.13 1847. His age is 33, hers is 23. This makes me believe Ann died between Dec 1846 and Dec 1847. But still that's a rather short turn around to get married again! Let me know if you ever run across something else that would shed some light on the situation.
