Looking for birth, marriage, and death dates and places for Benjamin Ladd and his wife, Joanna Fields. I have the marriage on 11 May 1868 in Searsmont, Waldo Co., Maine, of their daughter, Mary E. Ladd, (b. 4 Sep 1843, d. 20 Jun 1921) to Edward R. Packard (b. 13 Apr 1832, Searsmont, d. 28 Aug 1908, Searsmont). Edward was the son of Nathan Packard and Mary Chase. I have Edward's ancestry for anyone interested. Edward and Mary had a daughter, Ada Mabel, in 1871. Ada Mabel may be the one who married 17 Apr 1893 Horatio D. Crie of Matinicus Plantation, Criehaven Twp., Knox Co., Maine,I have nothng more about their descendants but am interested in obtaining more.
