I read your message on the Tower Gen Forum, and decided to try researching your ancestors.
I hope that this information helps.I wasn't able to determine if your Giddeon Tower was a descendant of John and Margaret Ibrook Tower line.However, I was quite interested to learn that there seemed to be quite a number those with the Tower last name in the Lincolnville, Waldo, Maine area. Once the Tower Genealogical Society forms a genealogical committee I hope to direct this information to their attention for further research.
Having researched the individuals that you listed in your Tower GenForum message, at: www.familysearch.org I was able to locate the following information; According to the 1880 USA Census:
