My wife was an Exelby, so I have done quite a bit of research on this name, and currently have over 2000 Exelbys on my file, although because of limited detail on some of these there may be duplications and some of them are not linked to anyone else.
If you would like to send me what you have (as much detail as possible), I will see if I can find any matches in my records that may add to your information.
