I seem to be finding cousins all over. The book my mom has isn't the one you are talking about. I emailed whit athey and the email was returned undeliverable.
as far as Clarence and Linda, my grandmother faye probably would know, i'll ask when i talk to her. I know that she still goes to a "cousins"reunion in Crowell each year. I will give her a call and find out when and where they are held.
ps you can email me direct at firstname.lastname@example.org
