Hi English, I have a copy of an 1867 Voting Registration of Loyalty Oaths / Individual Pardon Applications of Walker Co., Alabama. It includes residents of Walker Co., AL who signed loyalty oaths to the Union in 1867 and 1868. It lists several Davidsons from AL.. Not sure if this is what you are looking for but thought I would put this info on the list. I got this information from writing to Alabama Dept of Archives. Lynne Davidson Foster Pickens Co., AL
