I'm not related, but was looking into possible cemetery information on Green Flake here in Idaho Falls, ID at our Family History Library.He is not buried here (apparently in Union, Salt Lake, Utah), but I did find the following listings for family members:
Abraham Flake, 75, negro, b. 6 Jul 1860 Murray, UT, d. 28 Jan 1936 Idaho Falls, ID.Buried Rose Hill Cemetery.Post Register 28 Jan 1936 p. 3, & 3 Feb 1936 p. 6.Parents: Abraham Green Flake & Martha Ann Morris.
Mary Flake, d. 22 Dec 1916, Rose Hill Cemetery.Post Register 28 Dec 1916.Wife of Abraham Flake.
The public library has copies of the Post Register on film.
