Oh mercy, I’ve had this exact same problem with my crazy Southern names, especially my mountain families, names like Clarendy (f.) and Lusla (m.) and Reamer (f.) and Delphia (f.) and Jean (as a m.) Enneretter (f., a variant of Henrietta, spelled just like it was pronounced), and Cansadie (f). Fortunately for me, these occur only once each in my tree, but I don’t feel like explaining this to a computer (if I ignore it, will it go away?). Here names don’t even sound foreign to me as I grew up with these folks.
How about Jedon, a variant of Gideon. Uncle Jede’s true name shows up in his first census records, and Jedon in just about every record since.p, even his gravestone.
I get suggestions on these names all the time. At least the WT suggestion program doesn’t laugh at me for the rural, mountain names of my family like people do.
