Congratulations on your study. I'd like to add that Peasley et al. is often thought to be related to Beasley et al. In my research, I'm finding no such connection. In my research, it seems possible that there is an etymological relationship between Peasley and Paisley but I can't verify that. OTOH, I'm not seeing a relationship between Beasley and Baisley, however. I have had a Peasley apply to the Beasley YDNA study and I'd be happy to share with him information about your study. While I'm not in a position to participate in your study, nor am I asking you to participate in mine, I'd be happy to discuss questions of etymology and surname history.
