I understand completely, and I hope I didn't come off sounding dismissive -- not my intent at all. It's a lead, and those are always valuable in genealogy! I did find in digging about that Susannah (John William Wheeler's first wife) may have been a Drummond -- don't know if that's helpful to you or not, but thought I'd throw it out there. Also no primary documentation, but once again... a lead.
I'll keep looking -- and if you find more, please let me know. I've been after these folks for a long time!
