Thank you, ladies. I didn't see the original document, only the transcription on the LDS site. (It's the only free source I know to view Census information and I'm not in a position to pay for the other sites at the moment.)
The fact that Bonard was used at all made me think it was probably connected. The age threw me off, though it didn't seem like Britton would have named a child after his wife's (presumed?) dead husband, but that wasn't impossible.
Is it possible for one of you to contact me from there to work out sending me a copy of the original census document? I'd like to see it, too and would be very much appreciative.
I am still hoping someone out there knows more about Charlie himself - who he was, where he came from, and where he went. It's been presumed he died before Verlydia married Britton, but considering Verlydia and Britton divorce/separate within a few years or so of the 1880 Census, I don't throw out the possiblity that Charlie and Verlydia parted in a manner other than death.
Oh! Something that may or may not be pertinent here: I know through family legend that my great-grandfather Charlie Daniel (Ida's son) was part Cherokee and had a roll number. I've been told he sold his roll number "to a Gentry," which I presume a relative through Verlydia's 3rd husband, Levi Gentry. I have been able to reach back farther on Charlie Daniel's father's side already, so I suspect the Cherokee was through Ida. I have a photo of Verlydia and - well - she doesn't look Native American, but Cherokees were typically lighter than other Natives because they were more likely to mix with whites than some of the other tribes, so I can't really say just by looking at her. I wonder if Charlie Bonnard was the Cherokee?? I don't know how "part-Cherokee" my great-grandfather was to know how Cherokee his grandparent was, either, but hopefully this will shed some light for someone that may know more.
