I am sorry but I have very little information on Ann Tucker. What little information I do have is on my familytreemaker web site. Have you visited this site? The address is
http://familytreemaker.genealogy.com/users/t/r/u/Don-Trumbo-...
You can go there and click on "surname list" then "tucker" I would love to hear if you really think there could be a match. I have came to a dead end on her. I found the family in the 1841 census of Georgeham parrish. Also found marriage record through LDS in Devon England that lists her as Mary Ann Tucker. There is a picture of her grave marker on my website. Thank you for your response.
