Familysearch has Mary F. E. BRIGHTWELL Sex: F Spouse: Thomas KING, Marriage: 17 Jun 1860, Platte, Missouri. These might be the parents of John King, husband of Bertha Comstock.
Bertha Adele Comstock married John King before 1913. Bertha Comstock was the sister of George Comstock. The daughter of John and Bertha King is (Mary) Josephine King (1913 - 2000), who married Robert Hoopes, ?? Castro and then William B. Bramlett (my father).
Jo King was born in Fairbanks, Alaska. Her mother was, I think, from Illinois, or went to Alaska from Illinois. Jo King Hoopes' son was named also named Robert Hoopes (about 1938 to 1976). Bertha Adele Comstock King, George Comstock, Josephine King Bramlett and Robert Hoopes (the younger) are buried together in Rancho Palos Verdes, California. George and Robert had no children or spouses, I believe, and Bertha's only child was Josephine.
The mother of John King (or maybe the mother of Bertha Comstock) may have been Mary Brightwell. By family tradition, Josephine King Bramlett's ancestors include Daniel Boone. Are you related to any of these people? I would like to compare notes with you.
Familysearch.com has John Henry KING, Sex: M, Spouse: Bertha Adela COMSTOCK, Marriage: 23 Dec 1911, Of, Boscobel, Grant, Wisconsin, so maybe I'm wrong about the spelling of Bertha's middle name and about the Illinois origins.
