Hi Valerie,
Well, even with the extra info, I could not match him to one of the 19 William's we had. A couple were close with their age, but that state and wife was wrong. Eight of them did have a wife named Mary but no Lesson or anything close.
And still nothing on Asher using only his first name.
You appear to have quite a bit on these men, so with continued research you will probably have enought to submit an application. If you would like someone from DAR who is local to you to contact you , let me know.
Mary
