I do not know if you will get this; however... I am giving it a try..
the only Alice I have in a book I have is "Alice L. Ludden".. (siblings: Jennie, Josph, Fank, and Mabel).... Parents: Herbert Russell Ludden m. Sarah J. Sherman. Herbert's parents were: Joseph Tranquil Ludden and Elisa Brown. Joseph's parents were Joseph Ludden and Thankful Gott. (all of this is from book, located in libraries, called "James Ludden and Descendants" and is in the chapter "The Maine Luddens". However... I do not know if this is your grandmother for sure... just going with Ludden as maiden name and the particular chapter. No mention of Endfield at all.
