Hi, I'm not related at all but I thought I'd try to help dig up some info.
First off, I found at familysearch.org that Guy was Guy Willis Creighton born 23 Sep 1889 at York, Athens Co., OH.He was the son of Elza Creighton and Eliza Drain.That's all that was there.
Next, I looked up Knox Co., IN marriage records at ancestry.com and found Guy and Bessie's marriage date.Plus, I found two other Creighton's listed: Milford who married Ruby Rope on 31 Dec 1920 and Ruth who married E. Baughman on 27 Nov 1916.
Then I looked up birth records also at ancestry.com and found 4 Creighton's born in Knox Co., IN between 1882-1920: Joseph, born 2 Apr 1919, son of Samuel E. Creighton and Almyra B. Addis; Maynard D., born 8 Feb 1916, son of Samuel E. Creighton and Almyra B. Addis; Gerald F., born 9 Dec 1917, son of Guy Willis Creighton and Bessie F. Scott; Kenneth , son of Guy Willis Creighton and Bessie F. Scott.
Lastly, I looked up census records.I was never successful in finding Guy & Bessie on the 1920 or 1930 census but I did find other family members and I found Guy on the 1900 & 1910.
