...these suggestions are great and I did wonder the same thing. So far, I've not found any relatives with the surname Chaney, but I hadn't thought of looking for folks living nearby in general.
I didn't want to say anything too leading in my original post, but in the digital image of the hand-written marriage entry, her middle name, or names, is/are given as (best I can make out the penmanship)
Chris, with a small blob that could be a period, then a small space (not quite enough to definitively call a space between separate words), then what looks like chany or chary. The possible second middle name is definitely not capitalized the way the "
Chris" part is. In addition, my great grandmother had given her ancestor's name as
Harriet Christeny, which she pronouced kris-tee-nee. Because these ancestors had little or no schooling (many never learned to read and/or write), it can be tough to interpret their records. I never knew anything about her going by Chaney until I saw a photo of her grave stone and then spoke with a distant cousin who told me their family never knew her as anything other than Chaney.
I was curious whether Chaney was perhaps a known nickname for Christine/Christina/Christian type names. She is recorded variously in census records as
Christina (as a child),
Harriet and
Harriet C.
Thank you again for your assistance. I really appreciate it. :)
