Again, thank you so much for looking into this. If you have access to Ancestry, all the supporting evidence is posted in my tree under both Coleman and his wife Olive Catlin. Olive did live for a time in Overton, Pueblo, Colorado with her son Frank according to the 1900 census but moved to Santa Cruz, CA with her other son Milo by 1910.
Under Coleman in my tree, there's a handwritten note from Laura A Ford DuPee telling the story of where Coleman lived, how he died, and where he's buried. This was in a family photo album of Harley DuPee. I do not yet know how Laura is related to my family, but the note says she's Smith Godfrey's granddaughter. I have pictures of her and other family members Amasa Granson DuPee and his family in our albums. I don't know their connections to the family but they must be related or wouldn't be in our family photo albums!
Here's the direct link to that note: http://trees.ancestry.com/tree/32733225/person/18319692057/m...
Please let me know if this isn't working. Thanks!
