There is a book that may interest you. It's APPLETON'S CYCLOPEDIA OF AMERICAN BIOGRAPHY. Wilson, James Grant 1832-1914; Fiske, John1842-1901.New York; D. Appleton & Co. There is a publication on line from the University of Michigan Library, 2005.
Henry Larcom Abbot is listed in the book; possibly others. If you do a search for the site Making of America Books and then do a search of their site, I'm sure you'll find it. Henry's surname (in the book) is spelled as above.
I'm not researching this man or his family, I just ran across it and thought you may like the information.
