Hi Carol, I'm not related to this family, but I found a couple of things in the online old newspapers that might fill in a piece of missing info, if you don't already this.
From the obit for Mrs. Jackson Castator, it looks like she died on January 19, 1911...instead of 1916.
Also: Fort Wayne Journal-gazette, November 27, 1911 Jackson Castator of Albion in his seventy-third year was licensed to wed Melissa Jane Whitneck/Whitheck of Kendallville. Rev. L.G. Bears of this place performed the ceremony that made the latter couple man and wife. Mr. and Mrs. Castator celebrated his seventy-second birthday last spring by walking from Kendallville to Albion, a distance of twelve miles.
Fort Wayne News, September 29, 1914 Wesley Castator and family and Orrin Castator, of this city, attended the funeral of their nephew, Pierre Castator, at Goshen, Sunday, the young man having died in a hospital in Chicago. He was a son of William Castator, who was killed on the B & O railroad, near here, a number of years ago.Rollin Black and family of York township also attended the (obsequies?). Mr. Black was an uncle of the deceased.
Fort Wayne Journal-gazette, September 19, 1916 Mrs. Monroe Castator, of Washington township, ill since the first of the year with tuberculosis, passed away Saturday evening at the age of forty-one years. The deceased was born in Whitley county, her maiden name being Smith.
